probe: Replace VEC(probe_ops_cp) with std::vector

Make collect_probes return an std::vector
Change collect_probes so it returns an std::vector<bound_probe> instead
of a VEC(bound_probe_s). This allows removing some cleanups. It also
seems like enable_probes_command and disable_probes_command were not
freeing that vector.
The comparison function compare_probes needs to be updated to return a
bool indicating whether the first parameter is "less than" the second
parameter.
I defined two constructors to bound_probe. The default constructor is
needed, for example, so the instance in struct bp_location can be
constructed without parameters. The constructor with parameters is
useful so we can use emplace_back and pass the values directly.
The s390 builder on the buildbot shows a weird failure that I can't

This is likely due to a GCC bug, because for some reason the compiler
assumes that the third argument to the memset:
memset (regcache->register_status, REG_UNAVAILABLE,
VEC_length (tdesc_reg_p, regcache->tdesc->reg_defs));
is always zero, which is not always true.
Anyway, the simple fix for this is to guard the memset calls with:
if (!VEC_empty (tdesc_reg_p, regcache->tdesc->reg_defs))
This time, I made sure to regtest only this patch on BuildBot, and it

gdb: Remove check for gdb_stderr == NULL
Recent changes made gdb_stderr a macro:
#define gdb_stderr (*current_ui_gdb_stderr_ptr ())
and current_ui_gdb_stderr_ptr return this:
¤t_ui->m_gdb_stderr
The problem is that this is undefined if current_ui is NULL, which can
happen early on during gdb start up.
If we run into an error during early gdb start up then we write the
error message to gdb_stderr. However, if we are too early during the
start up then current_ui is NULL, and using the gdb_stderr macro
triggers undefined behaviour.
We try to avoid this using a check 'gdb_stderr == NULL' which was fine
before the recent changes, but now, still triggers undefined behaviour.
A better check is instead 'current_ui == NULL' which is what I use in
this patch.
Triggering this failure is pretty hard, most of the really early errors
are only triggered if pretty basic things are not as expected, for
example, if the default signal handlers are not as expected. Seeing one
of these errors trigger usually means that someone working on gdb has
made an incorrect change. Still, the errors are present in gdb, and
should we ever trigger one it would be nice if gdb didn't crash.
For testing this change I've been applying this patch which adds an
unconditional error into a function called early during gdb start up.
Later in the same function is a real error call which, in some
circumstances could be triggered:

Remove unnecessary calls to is_mi_like_p in print_thread_info_1
There are two calls to uiout->is_mi_like_p in the else branch of a

A bit lower, there are two if (!uiout->is_mi_like_p ()) that we can

RISC-V: Avoid emitting invalid instructions in mixed RVC/no-RVC code
When linking the following code
.global _prog_start
_prog_start:
mv x1, x1
mv x2, x2
.align 2
rvc_boundry:
.option norvc
.align 3
mv x3, x3
we currently emit an invalid two-byte 0 instruction. The actual output
code looks like
0000000080000000 <_prog_start>:

80000006: 0001 nop
80000008:
00018193 mv gp,gp
This ends up manifesting due to the two-byte compressed NOP that's
pessimisticly emitted by the ".align 2", which results in "rvc_boundry"
being 2-byte aligned. frag_align_code() then goes and outputs a 2-byte
NOP (which is invalid in no-RVC mode) to align the code back to a 4-byte
boundry, which can't be relaxed away by the linker as it's not part of
the R_RISCV_RELAX relocation.
The fix is to just always emit the worst case possible alignment into
the output as a single R_RISCV_RELAX, which the linker will then fix up.
With this patch I get the expected code generation
0000000080000000 <_prog_start>:

RISC-V: Support PCREL_* relocations agaist weak undefined symbols
I recently modified our Linux port's base address such the absolute
address 0 is no longer addressable as a 32-bit PC-relative offset.
Since Linux links a weak undefined symbol in an intermediate binary, it
needs to be able to reference absolute address 0.
This patch changes R_RISCV_PCREL_* relocations to absolute relocations
while resolving them in order to allow these symbols to be referenced in
PC-relative programs linked at high addresses. Note that this doesn't
apply to PIC, which also uses PC-relative relocations, just to
position-dependent objects, which we use to allow programs to be linked
at high addresses.
In case some of our embedded users are using R_RISCV_PCREL_* as a hacked
up method of getting position-independent binaries (which can work if
you have very simple programs), we only convert the relocations when the
PC-relative version would overflow.

Fix accessing TLS variables with no debug info
Since
2273f0ac95a7 ("change minsyms not to be relocated at
read-time"), printing TLS symbols of objfiles with a non-zero base
address, without debug info, fails.
E.g., with:
$ mv /usr/lib/debug /usr/lib/debug-x
to get debug info out of the way, we get:
$ echo 'int main(){}' | gcc -pthread -x c -
$ ./gdb -q -ex start -ex 'p (int) errno' ./a.out
Cannot access memory at address 0xffffef7c0698
instead of the expected:
$1 = 0
The regression is not visible with glibc debuginfo installed.
The problem is that we compute the address of TLS minsyms incorrectly.
To trigger the problem, it is important that the variable is in an
objfile with a non-zero base address. While glibc is a shared library
for 'errno', it's easier for the testcase to use PIE instead of a
shlib. For TLS variables in PT_EXEC the regression obviously does not
happen.

Add thread after updating gdbarch when exec'ing
As mentioned in the previous patch, we should avoid doing register reads
after a process does an exec and before we've updated that inferior's
gdbarch. Otherwise, we may interpret the registers using the wrong
architecture. When a process does an exec with "follow-exec-mode new",
a new inferior is added by follow_exec. The gdbarch of that new
inferior is at first set to some default value, probably specific to the
gdb build (I get "i386" here), which may not be the right one. It is
updated later by the call to target_find_description. Before that
point, if we try to read the inferior's registers, we may not interpret
them correctly. This has been exposed by a failure in
gdb.base/foll-exec-mode.exp after the previous patch, with:
Remote 'g' packet reply is too long (expected 312 bytes, got 816 bytes)
The call to "add_thread" done just after adding the inferior is
problematic, because it ends up reading the registers (because the ptid
is re-used, we end up doing a switch_to_thread to it, which tries to
update stop_pc). The registers returned by gdbserver are the x86-64
ones, while we try to interpret them using the "i386" gdbarch.
Postponing the call to add_thread to until the target
description/gdbarch has been updated seems to fix the issue.
As to why this issue was uncovered by the previous patch: what I think
happened before that patch is that since we were updating stop_pc before
switching to the new inferior, we were filling the regcache associated
to the ptid (this worked fine as long as the architectures of the
previous and new process images were the same). The call to
switch_to_thread then worked, because the register read hit the
regcache. Now, it triggers a register read, while the gdbarch is not
set correctly, leading to the "reply is too long" error. If this is
right, it sounds wrong that we delete and re-add a thread with the same
ptid, and are able to access the registers from the deleted thread.
When we delete a thread, should we clear the regcache associated to that
ptid, so that the new thread starts with a fresh/empty regcache?

Read stop_pc after updating the gdbarch when exec'ing
When an inferior execs and changes architecture (e.g. 64 bits to 32
bits), the gdbarch associated to the inferior is updated by the
follow_exec call in handle_inferior_event_1. We should avoid doing any
register read before that point, because the registers sent by the
remote side will be those of the new architecture, but we would
interpret them using the old architecture. We do just that by setting
stop_pc during this window, which obviously requires reading the
registers. This results in gdb.multi/multi-arch-exec.exp failing, GDB
outputting the following error:
Truncated register 50 in remote 'g' packet
