[libc++] Reduce the number of runs on the format_to{,n} and formatted_size benchmarks (#179922)
Testing a bunch of sizes has relatively little value. This reduces the
number of benchmarks so we can run them on a regular basis. This saves
~8 minutes when running the benchmarks.
[NFC][ELF] Fix overzealous find/replace affecting comments
Commit a94060ca0c87 ("[ELF] Pass Ctx & to Relocations") swapped the
InputSectionBase &c argument for an InputSectionBase *sec member, and so
"c." was replaced with "sec->". However, this must have done in such a
way that "Local-Exec." was transformed to "Local-Exesec->" and
"RISCV::relocateAlloc." to "RISCV::relocateAllosec->", i.e. without the
use of something like clangd, and without appropriate word boundaries in
a regex.
[AMDGPU] Fix instruction size for 64-bit literal constant operands (#180387)
`getLit64Encoding` uses a different approach to determine whether 64-bit
literal encoding is used, which caused a size mismatch between the
`MachineInstr` and the `MCInst`.
For `!isValid32BitLiteral`, it is effectively `!(isInt<32>(Val) ||
isUInt<32>(Val))`, which is `!isInt<32>(Val) && !isUInt<32>(Val)`, but
in `getLit64Encoding`, it is `!isInt<32>(Val) || !isUInt<32>(Val)`.
[MLIR][Python] Support dynamic traits in python-defined dialects (#179705)
This is a follow-up PR of #169045 and the second part of #179086.
In #179086, we added support for defining regions in Python-defined ops,
but its usefulness was quite limited because we still couldn’t mark an
op as a `Terminator` or `NoTerminator`. In this PR, we port the
`DynamicOpTrait` (introduced on the C++ side for `DynamicDialect` in
#177735) to Python, so we can dynamically attach traits to
Python-defined ops.
[LifetimeSafety] Add fixit verification with FileCheck (#180488)

[InstCombine] fold `gepi _, (srem x, y)` to `gepi _, (urem x, y)` if `y` is power-of-2 (#180148)
This PR adds a small, targeted InstCombine fold for the pattern:
```
%idx = srem i64 %x, 2^k
%p = getelementptr inbounds nuw i8, ptr %base, i64 %idx
```
When the GEP is inbounds + nuw, and the divisor is a non-zero
power-of-two constant, the signed remainder cannot produce a negative
offset without violating the inbounds/nuw constraints. In that case we
can canonicalize the index to a non-negative form and expose the common
power-of-two rewrite:
- Rewrite the GEP index from `srem %x, 2^k` to `urem %x, 2^k`
- Create a new GEP with the new index and replace the original GEP
- the `urem %x, 2^k` will further folds to `and %x (2^k-1)`
resulting the following pattern

[CostModel][X86] getShuffleCost - SK_Transpose v4f64/v4i64 matches UNPCK - don't generalise to SK_PermuteTwoSrc (#180514)

NAS-139686 / 26.0.0-BETA.1 / Only enter user namespace in nsenter when container has idmap (#18161)
## Problem
Privileged containers do **not** use user ID mappings (`idmaps`).
However, the current implementation applies the `--user` flag to **all**
containers, including privileged ones.
This causes incorrect behavior for privileged containers, since the
`--user` flag is only meaningful and valid when user namespace mappings
are in use.
## Solution
Update container startup logic to:
* Apply the `--user` flag **only for non-privileged containers**
* Skip adding the flag for privileged containers that do not use ID
mappings
[SPIRV] Fix constant materialization for width > 64bit (#180182)
selectConst() was asserting for constants wider than 64 bits. Add APInt
overloads of getOrCreateConstInt and getOrCreateConstVector that avoid
the uint64_t truncation.
Revert "[VPlan] Add missing REQUIRES: asserts to VPlan output test"
This reverts commit 2805c8aaa61a94ef22ac76c8dac56f7dfe970651.
This added the REQUIRES line to the wrong test, 041ce9f added it to the
correct one.

[AMDGPU] Fix instruction size for 64-bit literal constant operands
PR #156602 changed the condition for using 64-bit literal encoding, but it
didn't update the instruction size calculation. This caused a size mismatch
between the `MachineInstr` and the `MCInst`.
[lldb] add cross platform test commands in Makefile.rules (#180224)
This patch adds cross platform (Darwin, Linux, Windows) commands in
`Makefile.rules` which is used to build lldb test targets.
This maps POSIX commands like `mkdir -p` to their Windows equivalent,
which allows to create cross platform `Makefile` for lldb's test
targets. This is currently not needed by any test but might become
useful later as we are working on enabling more lldb Windows tests.
This was originally done in the `swiftlang/llvm-project` fork
(https://github.com/swiftlang/llvm-project/pull/12127)
