[CodeGen] Introduce MI flag for Live Range split instructions
For some targets, it is required to identify the COPY instruction
corresponds to the RA inserted live range split. Adding the new
flag `MachineInstr::LRSplit` to serve the purpose.
[AMDGPU] Regenerate all MC checks after #164424 (#175156)
Includes one manual fix to add -filetype=null to a RUN line in
test/MC/AMDGPU/gfx1250_asm_sop1.s. Everything else is autogenerated.
[OpenMP][flang] Move `todo` for checking reduction support status on the GPU
Moves a `todo` to check for the current level of support for by-ref
reductions to the `FunctionFiltering` pass. This guarantees that the
check does not trigger when the same module is compiled twice: on the
CPU and on the GPU.

[mlir][Analysis][NFC] Improve `RegionBranchOpInterface` API usage (#173983)
Remove a helper function and query the `RegionBranchOpInterface`
instead. (Which does the same thing.) Also add a TODO for a bug in the
implementation of `SliceWalk.cpp`. (The bug is not fixed yet.)

[clang] Fix string literal parsing on some attributes (#171017)
At the time ParseAttributeArgumentList is called, the first argument
of an attribute may have already been parsed. We need to take this into
account when accessing ParsedAttributeArgumentsProperties mask, which
specifies which of the attribute arguments are string literals.

[flang-rt][build] Disable build-time warning of '-Wshift-count-negative' from g++ compiler and remove unsupported floating-point data. (#174915)
When building the flang-rt project with the g++ compiler on Linux-X86_64
machine, the compiler gives the following warning:
```
llvm-project/flang-rt/lib/runtime/extensions.cpp:455:26: warning: left shift count is negative [-Wshift-count-negative]
455 | mask = ~(unsigned)0u << ((8 - digits) * 4 + 1);
| ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~

[AllocToken] Fix attribute mismatch in AllocTokenPass (#174959)
Fixes an attribute mismatch error in `AllocTokenPass` that occurs during
ThinLTO builds at OptimizationLevel::O0.
The `getTokenAllocFunction` in `AllocTokenPass` was incorrectly copying
attributes from the instrumented function (`Callee`) to an *existing*
`void()` alloc-token function retrieved by `Mod.getOrInsertFunction`.
This resulted in arg attributes being added to a function with no
parameters, causing `VerifyPass` to fail with "Attribute after last
parameter!".
The fix modifies `getTokenAllocFunction` to pass the `Callee`'s
attributes directly to the `Mod.getOrInsertFunction` overload. This
ensures attributes are only applied when the alloc-token function is
*newly inserted*, preventing unintended attribute modifications on
already existing function declarations.

[MLIR][NVVM] Fix crash on invalid optimization level in NVVMTargetAttr (#173280)
Update `NVVMTargetAttr` builder in `NVVMOps.td` to use `$_get` instead
of `Base::get`.
Now the auto-generated parser calls `getChecked`, allowing graceful
error handling for invalid parameters (e.g., `O=4`) instead of crashing
with an assertion failure.
Add a regression test in
`mlir/test/Dialect/LLVMIR/nvvm-target-invalid.mlir`.

py-virtualenv: updated to 2.36.0
Features - 20.36.0
Add support for PEP 440 version specifiers in the --python flag. Users can now specify Python versions using operators like >=, <=, ~=, etc. For example: virtualenv --python=">=3.12" myenv .
