[libc][math] Add LIBC_CONF_MATH_USE_SYSTEM_FENV / LIBC_MATH_USE_SYSTEM_FENV (#172902)
This is to allow math function implementations to use system libc's
fenv.h instead of internal fenv implementations.
[VectorCombine] foldPermuteOfBinops - support multi-use binary ops and operands in shuffle folding (#173153)
Fixes #173033
This patch extends VectorCombine to fold binary operations through
shuffles in scenarios involving multiple uses of both the binary
operator and its operands.
Previously, the transformation was restricted to single-use cases to
prevent instruction duplication. This change implements a cost-based
evaluation that allows the fold even when:
1. The binary operator has multiple users (requiring duplication of the
arithmetic instruction).
2. The operands of the binary operator (the shuffles) have multiple
users (requiring the original shuffles to be preserved).
The optimization is performed if the TTI cost of the new instruction
sequence—including any duplicated arithmetic—is lower than the cost of
the shuffle sequence it replaces. This is particularly beneficial on X86
targets for expensive cross-lane shuffles.
Improve handling of SMB paths for HA systems
This commit shifts the majority of SMB-related paths that aren't
required for SMB session persistence to the boot pool. This
enables the standby controller to more readily be prepared to take
over sessions because we have to resync fewer items on failover
and don't have to replace winbindd / sssd state and flush caches.

Avoid merging globals residing in different comdats (#172835)
The global-merge pass may merge globals residing in different comdat
groups, which may later confuse linker if section GC is being used. In
particular this may happen when merging instrumentation profiler
counters when their corresponding __llvm_prf_cnts sections are being
merged into a single one and moved out of a comdat group, containing
__llvm_prf_cnts and __llvm_prf_data sections. After that __llvm_prf_data
section is becoming orphaned and is garbage-collected when --gc-sections
linker flag is used.

fusefs: Fix further intermittency in the BadServer.ShortWrite test case
After being unmounted, the mockfs server would occasionally read from
/dev/fuse again, if the main function didn't exit fast enough, getting
an ENODEV error. Handle that appropriately.

[LifetimeSafety] Add missing origins stats for lifetime analysis (#166568)
This PR adds the implementation for printing missing origin stats for
lifetime analysis.
**Purpose:**
This capability is added to track the expression types with missing
origin. While retrieving the origins from origin manager, some
expressions show missing origins. Currently these are created on the fly
using getOrCreate function. For analysing the coverage of the check, it
will be necessary to see what kind of expressions have a missing origin.
It prints the counts in this form: `QualType : count` and `StmtClassName
: count`.
**Approach:**
1. The signature of the runLifetimeAnalysis function is changed to
return the LifetimeAnalysis object which will be used to get the origin
