[tsan] Introduce Adaptive Delay Scheduling to TSAN (#178836)

This commit introduces an "adaptive delay" feature to the
ThreadSanitizer runtime to improve race detection by perturbing thread
schedules. At various synchronization points (atomic operations,
mutexes, and thread lifecycle events), the runtime may inject small
delays (spin loops, yields, or sleeps) to explore different thread
interleavings and expose data races that would otherwise occur only in
rare execution orders.

This change is inspired by prior work, which is discussed in more detail
on

https://discourse.llvm.org/t/rfc-tsan-implementing-a-fuzz-scheduler-for-tsan/80969.
In short, https://reviews.llvm.org/D65383 was an earlier unmerged
attempt at adding a random delays. Feedback on the RFC led to the
version in this commit, aiming to limit the amount of delay.

The adaptive delay feature uses a configurable time budget and tiered

[SPIRV] Rounding Mode decorations in OpenCL builtins only make sense when floating point types are involved (#181208)

The backend was adding fp-rounding mode flags to
`uchar convert_uchar_rte(uint)`. These builtins are equivalent to `uchar
convert_uchar(uint)` which simply truncates its input, since there is no
floating-point value involved.

Related to https://github.com/llvm/llvm-project/issues/180936

This is consistent with what was implemented in the translator in

[Clang] make most enums trivially equality comparable (#169079)

std::equal(std::byte) currently has sub-optimal codegen due to enum
types not being recognized as trivially equality comparable. In order to
fix this we make them trivially comparable. In the process I factored
out into a standalone function EqualityComparisonIsDefaulted and
refactored the test cases.

Enum types cannot have operator== which is a hidden friend.

The test fails on targets that have a different LLVM IR lowering (e.g.
RISC-V which produces `signext i32` for the return type). Rather than
complicate the test with more complex patterns, just set the triple
explicitly to x86-64 (as various other generic clang/test/CodeGen* tests
do).

Test was introduced by #163666.

This fixes RISC-V CI.

[Flang][OpenMP] Don't generate code for unreachable target regions. (#178937)

When a target region is placed inside a constant false condition (e.g.,
`if (.false.)`), the dead code gets eliminated on the host side,
removing the `omp.target` operation entirely. However, the device-side
compilation pipeline is unaware of this elimination and attempts to
generate kernel code. Since the host never created offload metadata for
the eliminated target, the device-side kernel function lacks the
"kernel" attribute, causing `OpenMPOpt` to fail with an assertion when
it expects all outlined kernels to have this attribute. The problem can
be seen with the following code:

```fortran
program cele
  implicit none
  real :: V
  integer :: i
  if (.false.) then
    !$omp target teams distribute parallel do

[SCEVDivision] Prevent propagating nowrap flags when numerator is an addrec (#154745)

In ScalarEvolutionDivision, when the numerator is an addrec, its nowrap
flags are unconditionally propagated to the quotient and remainder.
However, this is not always correct.
This pass is only used by Delinearization, and just dropping these flags
doesn't affect Delinearization's accuracy in almost all cases.
Therefore, this patch conservatively stop propagating the nowrap flags
from the numerator to the quotient and remainder.

[Support] Fixup for formatting hex on 32 bit (#181338)

Without the `PRIx64`, the test won't work on 32 bit architectures.

See this comment:
https://github.com/llvm/llvm-project/pull/180498#issuecomment-3891979182

The issue is that `PRIx64` expands differently depending on the
architecture. In the original code modified in #180498 the [macro was
used](https://github.com/llvm/llvm-project/pull/180498/changes#diff-5dcf6451d2bf9e9e3a8d28b0212263a8db576045b1d4eab80cca1bfd13a3bb76L356):

```diff
-  OS << format("0x%*.*" PRIx64, HexDigits, HexDigits, Address);
+  OS << formatv("0x{0:x-}",
+                fmt_align(Address, AlignStyle::Right, HexDigits, '0'));
```

I simply didn't use it in my test because on my architecture the
`PRIx64` wasn't necessary.

[clang-repl] Fix disambiguation of out-of-line member with private types (#178842)

This patch fixes a bug in clang-repl where out-of-line member function
definitions were incorrectly identified as statements when they involved
private type aliases.

The issue occurred because `isCXXDeclarationStatement` would trigger
immediate access checks during tentative parsing. Since the context of
an out-of-line definition isn't fully established during this phase,
Sema would incorrectly flag private members as inaccessible, causing
the parser to fail the declaration check and fall back to statement
parsing.

Changes:
- In `isCXXDeclarationStatement`, use `TentativeParsingAction` to
  ensure the token stream is fully restored.
- Use `SuppressAccessChecks` during the tentative disambiguation phase
  to prevent premature access errors.
- Ensure that formal access verification still occurs during the
