[AArch64][DAG] Copy flags when narrowExtractedVectorBinOp-ing (#193446)
The `extract (binop B0, B1), N` fold above already copies flags, use the
same for the `extract (binop (concat X1, X2), Y), N` version. In this
case it is helping copy disjoint or flags.
[AArch64][llvm][clang] Remove `int_aarch64_sve_bfmmla` and reuse existing def (NFC) (#193970)
Remove the dedicated (superfluous) `int_aarch64_sve_bfmmla` def and
changed `svbfmmla` to use the existing shared fmmla intrinsic instead.
No functional change.
[Clang][Coroutines] Don't emit fake uses for coroutine parameters (#194690)
Fixes issue: https://github.com/llvm/llvm-project/issues/192351
The combination of coroutines with -fextend-variable-liveness has
resulted in use-after-free, caused by the fact that we insert fake uses
of coroutine parameters at the end of the coroutine. While this is fine
for normal functions, in coroutines these variables are stored in the
coroutine frame, which is freed before the end of the function; this
results in us loading from the deleted frame.
This patch fixes this by no longer emitting fake uses for most coroutine
parameters. Since coroutine parameters will be saved back to the frame
when we suspend, and currently may not be optimized out, fake uses are
not needed in this case, and so by not emitting them we avoid dealing
with the complexity of updating fake uses in the CoroSplit pass. The
exception to this is 'this', which is not saved to the frame.

[AArch64] Use add_like for UMLAL / SMLAL (#194139)
Similar to the others, this allows us to generate UMLAL and SMLAL from
add-like disjoint ors. There are some cases where we lose the disjoint
from the or, those are being fixed separately (#193446).
[LV] Use isLegalMaskedLoadOrStore for interleaved accesses too (NFC)
isLegalMaskedLoadOrStore is now the central place for querying target
capabilities for masked accesses. Access pattern legality checks are
hoisted outside of it.
[LV] Introduce isLegalMaskedLoadOrStore (NFC)
This simplifies legality checks, and eventually will become the single
point querying TTI hooks for masked ld/st. Currently, legality checks
for interleaved accesses still query TTI directly.
[AArch64] Extend SBC combine to handle CSET HI (#192708)
The `performSubWithBorrowCombine` previously only matched `CSET LO`
(unsigned <).
This extends it to also handle `CSET HI` (unsigned >) by swapping the
`SUBS` operands, since `a > b` is equivalent to `b < a`.
This resolves the FIXME left in the test from #165271.
[lldb][debugserver] ifdef guard around newer CPU_TYPEs (#195225)
The uses of the new CPU_SUBTYPEs depends on building with a newer SDK
that we don't have on Intel CI bots. Put idef guards around them,
debugserver won't be
working with these CPUs either way.
[lldb] Override UpdateBreakpointSites in ProcessGDBRemote to use MultiBreakpoint
This concludes the implementation of MultiBreakpoint by actually using
the new packet to batch breakpoint requests.

[lldb] Implement delayed breakpoints (#192971)
This patch changes the Process class so that it delays *physically*
enabling/disabling breakpoints until the process is about to
resume/detach/be destroyed, potentially reducing the packets transmitted
by batching all breakpoints together.
Most classes only need to know whether a breakpoint is "logically"
enabled, as opposed to "physically" enabled (i.e. the remote server has
actually enabled the breakpoint). However, lower level classes like
derived Process classes, or StopInfo may actually need to know whether
the breakpoint was physically enabled. As such, this commit also adds a
"IsPhysicallyEnabled" API.
The following PRs are related to the MultiBreakpoint feature:
* https://github.com/llvm/llvm-project/pull/192910
* https://github.com/llvm/llvm-project/pull/192914
* https://github.com/llvm/llvm-project/pull/192915

[libc][NFC] Replace <sys/mman.h> with proxy headers in mman (#195164)
Replaced direct <sys/mman.h> includes in sys/mman entrypoint headers
with granular proxy headers (hdr/types/size_t.h). The mmap.h entrypoint
header retains its transitive sys/mman.h include, keeping tests working.
Updated mremap.cpp and posix_madvise.cpp to include
hdr/sys_mman_macros.h for mman macros used directly.
