AArch64: Add SVE constraints verifier.
This patch adds the verification rules for move prefix constraints.
The Arm SVE instruction MOVPRFX introduces[1] constraints on the instruction at
PC+4. Particularly the following constraints are handled by this patch
* MOVPRFX must be followed by an instruction.
* MOVPRFX can only be followed by non-layout altering directives.
* MOVPRFX destination register MUST be used as the destination register in the
instruction at PC+4, and is not allowed to be used in any other position other than
destructive input. This includes registers that architecturally overlap. e.g. x1
should be treated as z1.
* MOVPRFX must be followed by a restricted set of SVE instructions.
* The size of the destination register of MOVPRFX must be equal to that of
the operation at PC+4.
* The predicate register and operation of MOVPRFX must match that of the instruction
at PC+4
* The predicated instruction at PC+4 must use the merging predicate.
* Architectural aliases and pseudo-instructions need to be supported as well.
* MOVPRFX cannot be the last instruction in a sequence
Any failure to adhere to any of these constrains will emit an assembly warning
and a disassembly note.

AArch64: Mark sve instructions that require MOVPRFX constraints
This patch series is to allow certain instructions such as the SVE MOVPRFX
instruction to apply a constraint/dependency on the instruction at PC+4.
This patch starts this off by marking which instructions impose the constraint
and which instructions must adhere to the constraint. This is done in a
generic way by extending the verifiers.
* The constraint F_SCAN indicates that an instruction opens a sequence and imposes
a constraint on an instructions following it. The length of the sequence depends
on the instruction itself and it handled in the verifier code.
* The C_SCAN_MOVPRFX flag is used to indicate which constrain the instruction is
checked against. An instruction with both F_SCAN and C_SCAN_MOVPRFX starts a
block for the C_SCAN_MOVPRFX instruction, and one with only C_SCAN_MOVPRFX must
adhere to a previous block constraint is applicable.
The SVE instructions in this list have been marked according to the SVE
specification[1].

The RISC-V memory model has been ratified, and it includes an additional

Thus there is no reason to allow this instruction to be disabled (or

Use the existing instruction to determine the RISC-V breakpoint kind.
RISC-V supports instructions of varying lengths. Standard existing
instructions in the base ISA are 4 bytes in length, but the 'C'
extension adds support for compressed, 2 byte instructions. RISC-V
supports two different breakpoint instructions: EBREAK is a 4 byte
instruction in the base ISA, and C.EBREAK is a 2 byte instruction only
available on processors implementing the 'C' extension. Using EBREAK
to set breakpoints on compressed instructions causes problems as the
second half of EBREAK will overwrite the first 2 bytes of the
following instruction breaking other threads in the process if their
PC is the following instruction. Thus, breakpoints on compressed
instructions need to use C.EBREAK instead of EBREAK.
Previously, the riscv architecture checked the MISA register to
determine if the 'C' extension was available. If so, it used C.EBREAK
for all breakpoints. However, the MISA register is not necessarily
available to supervisor mode operating systems. While native targets
could provide a fake MISA register value, this patch instead examines
the existing instruction at a breakpoint target to determine which
breakpoint instruction to use. If the existing instruction is a
compressed instruction, C.EBREAK is used, otherwise EBREAK is used.

gdb: Change how frames are selected for 'frame' and 'info frame'.
The 'frame' command, and thanks to code reuse the 'info frame' and
'select-frame' commands, currently have an overloaded mechanism for
selecting a frame.
These commands take one or two parameters, if it's one parameter then
we first try to use the parameter as an integer to select a frame by
level (or depth in the stack). If that fails then we treat the
parameter as an address and try to select a stack frame by
stack-address. If we still have not selected a stack frame, or we
initially had two parameters, then GDB allows the user to view a stack
frame that is not part of the current backtrace. Internally, a new
frame is created with the given stack and pc addresses, and this is
shown to the user.
The result of this is that a typo by the user, entering the wrong stack
frame level for example, can result in a brand new frame being viewed
rather than an error.
The purpose of this commit is to remove this overloading, while still
offering the same functionality through some new sub-commands. By
making the default behaviour of 'frame' (and friends) be to select a
stack frame by level index, it is hoped that enough
backwards-compatibility is maintained that users will not be overly
inconvenienced.
The 'frame', 'select-frame', and 'info frame' commands now all take a
frame specification string as an argument, this string can be any of the
following:
(1) An integer. This is treated as a frame level. If a frame for
that level does not exist then the user gets an error.
(2) A string like 'level <LEVEL>', where <LEVEL> is a frame level
as in option (1) above.
(3) A string like 'address <STACK-ADDRESS>', where <STACK-ADDRESS>
is a stack-frame address. If there is no frame for this address
then the user gets an error.
(4) A string like 'function <NAME>', where <NAME> is a function name,
the inner most frame for function <NAME> is selected. If there is no
frame for function <NAME> then the user gets an error.
(5) A string like 'view <STACK-ADDRESS>', this views a new frame
with stack address <STACK-ADDRESS>.
(6) A string like 'view <STACK-ADDRESS> <PC-ADDRESS>', this views
a new frame with stack address <STACK-ADDRESS> and the pc <PC-ADDRESS>.
This change assumes that the most common use of the commands like
'frame' is to select a frame by frame level, it is for this reason
that this is the behaviour that is kept for backwards compatibility.
Any of the alternative behaviours, which are assumed to be less used,
now require a change in user behaviour.
The MI command '-stack-select-frame' has not been changed. This
ensures that we maintain backwards compatibility for existing
frontends.

Remove a spurious target_terminal::ours() from windows_nat_target::wait()
This causes the inferior to stop with SIGTTIN if it tries to read from the
terminal after it has been continued.
See https://cygwin.com/ml/cygwin/2016-09/msg00285.html for reproduction.
Since MinGW doesn't have a tcsetpgrp(), I don't think this problem would be
observed there, but Cygwin does so target_terminal::ours() will call it.
Calling target_terminal::ours() here seems to be is no longer appropriate
after the "Merge async and sync code paths" changes (as the inferior is now
in a separate process group even in sync mode(?), which is always used on
Windows targets)
This call was added in commit
c44537cf (and see
https://sourceware.org/ml/gdb-patches/2007-02/msg00167.html for what it
fixed, which is not regressed by this change)
When windows_nat_target::wait() is entered, the inferior is running (either
it's been just been started or attached to, or windows_continue() was
called), so grabbing the controlling terminal away from it here seems to be
wrong, since infrun.c takes care of calling target_terminal::ours() when the
inferior stops.

More Solaris procfs cleanup
This procfs.c (and friends) cleanup patch grew along a couple of lines:
* First I noticed that PR_MODEL_NATIVE is always defined now that
Solaris 10 is the minimum supported version.
* Then there was a cleanup that I'd missed when removing support for
!NEW_PROC_API, IRIX, and Tru64 UNIX: given that sysset_t is no longer
dynamic, there's no need for the special sysset_t_alloc, but we can
just use XNEW instead.
* Then I found one of those ARI warning mails on gdb-patches, discovered
how to run it myself and fixed a large number of the warnings, among
them all uses of sprintf.
I had to silence the warnings in only 3 instances of the same issue,
namely references to LDT in function names which are due to the
libthread_db API.
* Even so, there were several formatting glitches, like braces around
single statements in an if, which I chose to fix while I was at it.
The result has been tested on amd64-pc-solaris2.11 and
