[AMDGPU] Optimize S_SETREG_IMM32_B32 piggybacking by treating it as a mode scope boundary (#184703)
When `handleSetregMode` encounters an `S_SETREG_IMM32_B32` with `Size <=
12`, the instruction's `imm32[12:19]` bits are "free" for VGPR MSB
piggybacking. Previously, the old mode was eagerly written into these
bits, but the `Rewritten` guard in `setMode` would then block subsequent
piggybacking when the next VGPR instruction needed a different mode,
causing an unnecessary `S_SET_VGPR_MSB` to be emitted.
Model the `S_SETREG_IMM32_B32` as the boundary of the old mode's control
range: reset `CurrentMode` and clear `bits[12:19]` to zero. This lets
the next `setMode` call freely piggyback the required mode without
triggering `Rewritten`.
Add a test for handling a crashing breakpoint condition (#184247)
I was working on something and broke the handling of breakpoint
conditions that crash. In fixing that I noticed that there wasn't a test
for this scenario, so this PR adds one.

[SafeStack] Fix crashing with scalable TypeSizes (#180547)
On e.g. aarch64 the TypeSize of scalar types can have a size that is not
known at compile time.
Currently when safestack occurs those it simply crashes as described in
https://github.com/llvm/llvm-project/issues/175868.
Since we cannot verify the size at compile time we simply consider the
access to be unsafe (in regards to safestack).
Reproducer:
```
#include <arm_sve.h>
int main() {
svint32_t vec = svindex_s32(0, 1);
svint32_t res = svadd_s32_z(svptrue_b32(), vec, vec);
int32_t buffer[1024];
svst1_s32(svptrue_b32(), buffer, res);

[lldb] Fix the AArch64 CPSR reg defn to list generic reg
My change to remove an incorrect DWARF register number for
CPSR unintentionally dropped the LLDB_REGNUM_GENERIC_FLAGS
generic reg type in the definitions of cpsr.
We need to have a macro (DEFINE_MISC_REGS) for status/control
registers that have no DWARF/eh_frame and no generic reg num.
I added a new macro, DEFINE_GPR_CPSR, for cpsr which is unique
in having no DWARF/eh_frame numbers but does have a generic
flags reg number.
[llvm][Support] Make createUniquePath require at least one wildcard marker (#184688)
The API was a bit easy to accidentally mis-use, as it silently accepted
Model strings without any randomness marker characters (`%`), which
results in a unique path that's not at all unique. To avoid this
foot-gun, we now assert that the model contains at least one, and update
all the broken usages accordingly.

[CIR][NFCI] Fixup some test regressions due to OGCG changes (#184699)
Discovered during CI in a different patch, 3 tests started failing for
unknown reasons due to some very mild changes to the IR, but only in
'classic' codgen parts of the tests. These tests were overly specific
for no good reason, so this patch just fixes that.
