disasm: add struct disasm_insn to describe to-be-disassembled instruction
The "record instruction-history" command prints for each instruction in
addition to the instruction's disassembly:
- the instruction number in the recorded execution trace
- a '?' before the instruction if it was executed speculatively
To allow the "record instruction-history" command to use GDB's disassembly
infrastructure, we extend gdb_pretty_print_insn to optionally print those
additional fields and export the function.
Add a new struct disasm_insn to add additional fields describing the
to-be-disassembled instruction. The additional fields are:
number an optional instruction number, zero if omitted.
is_speculative a predicate saying whether the instruction was
executed speculatively.
If non-zero, the instruction number is printed first. It will also appear
as a new optional field "insn-number" in MI. The field will be present if
insn_num is non-zero.
If is_speculative is set, speculative execution will be indicated by a "?"
following the new instruction number field. Unless the PC is omitted, it
will overwrite the first byte of the PC prefix. It will appear as a new
optional field "is-speculative" in MI. The field will contain "?" and will
be present if is_speculative is set.
The speculative execution indication is guarded by a new flag
DISASSEMBLY_SPECULATION.
Replace the PC parameter of gdb_pretty_print_insn with a pointer to the above
struct. GDB's "disassemble" command does not use the new fields.

Don't displaced step when there's a breakpoint in the scratch pad range
Assuming displaced stepping is enabled, and a breakpoint is set in the
memory region of the scratch pad, things break. One of two cases can
happen:
#1 - The breakpoint wasn't inserted yet (all threads were stopped), so
after setting up the displaced stepping scratch pad with the
adjusted copy of the instruction we're trying to single-step, we
insert the breakpoint, which corrupts the scratch pad, and the
inferior executes the wrong instruction. (Example below.)
This is clearly unacceptable.
#2 - The breakpoint was already inserted, so setting up the displaced
stepping scratch pad overwrites the breakpoint. This is OK in
the sense that we already assume that no thread is going to
executes the code in the scratch pad range (after initial
startup) anyway.
This commit addresses both cases by simply punting on displaced
stepping if we have a breakpoint in the scratch pad range.
The #1 case above explains a few regressions exposed by the AS/NS
series on x86:

the same failures with "maint set target-non-stop off + set displaced

Simplify gdb.threads/wp-replication.exp on counting HW watchpoints
Nowadays, test gdb.threads/wp-replication.exp uses a while loop to
repeatedly insert HW watchpoint, resume and check no error message
coming out, in order to count HW watchpoints There are some
drawbacks in this way,
- the loop could be endless. I think this is use to making trouble
to S/390, since we had such comment
# Some targets (like S/390) behave as though supporting
# unlimited hardware watchpoints. In this case we just take a
# safe exit out of the loop.
I hit this today too because a GDB internal error is triggered
on "continue" in the loop, and $done is 0 invariantly, so the loop
can't end.
- the code counting hardware watchpoint is too complicated. We can
use "set breakpoint always-inserted on" to get the result of inserting
HW watchpoint without resuming the inferior. In this way,
watch_count_done and empty_cycle in c file is no longer needed.
In this patch, I change to use "set breakpoint always-inserted on" trick,
and only iterate $NR_THREADS times, to count the HW watchpoint. In this
way, the loop can't be endless, and GDB doesn't need to resume the inferior.

The "theclass" local is of type enum address_class, however, what it
really holds is an address class index. Class index values by design
match the address class values up until LOC_FINAL_VALUE, but extend
beyond that, so it's not really right to store an address class index
in an enum address_class.
The fix is really the same making the 'theclass' local be of type int,

becomes the 'aclass_index' parameter in the new add_data_symbol

Don't assume break/continue inside a TRY block works
In C++, this:
try

catch (..)

the C++ version of those macros support it too. To catch such
assumptions, this adds a (disabled) hack that maps TRY/CATCH to raw
C++ try/catch. Then it goes through all instances that building on
x86_64 GNU/Linux trips on, fixing them.

target_read_memory&co: no longer return target_xfer_status
Years ago, these functions used to return errno/EIO. Later, through a
series of changes that intended to remove native/remote differences,
they ended up returning a target_xfer_status in disguise.
Unlike target_xfer_partial&co, the point of target_read_memory&co is
to either fully succeed or fail. On error, they always return
TARGET_XFER_E_IO. So there's no real point in casting the return of
target_read_memory to a target_xfer_status to pass it to memory_error.
Instead, it results in clearer code to simply decouple
target_read_memory&co's return from target_xfer_status.

ctf.c: Fix int/enum implicit cast
This patch was taken directly from Pedro's branch.
Right now, SET_INT32_FIELD is used to set enum fields. This works in C,
but not C++. Therefore, define the new SET_ENUM_FIELD, which casts the
value to the right enum type.
gdb/ChangeLog:
* ctf.c (SET_ENUM_FIELD): New macro.
(ctf_read_status): Use it.
(ctf_read_tp): Use it.
