[IR] Check FMF in isIdenticalTo() (#232805)
isIdenticalTo() is supposed to check that poison-generating flags are
the same. This accidentally broke when FastMathFlags move out of
SubclassOptionalData.
As a side-note, the transform in question should really be using
isIdenticalToWhenDefined() and intersecting flags, but that's a separate
issue...
Fixes https://github.com/llvm/llvm-project/issues/231487.
[mlir] Track known constant insertion effects (#232574)
Report whether inserting a known constant leaves the IR unchanged,
hoists the operation, or replaces it with an existing constant.
Use this result to accurately track IR changes in the greedy rewrite driver.

[CIR][NFC] Cache the CIRDataLayout in CIRGenModule (#232886)
... instead of rebuilding it. This fix a long standing FIXME.
The spec is fixed after Initialize and layout is only queried on
complete records (struct queries assert this and union queries never see
incomplete records in the test suite), so the cache stays valid for the
whole compilation. Also, CIRGen itself is single-threaded.
Compile time gains here are marginal, ~15% of CIRGen wall time on some
cases (SemaExpr.cpp, 66.2s to 65.4s (-0.8s), median of 3 runs).
[LV] Add tests for early-exit loops with reductions (NFC) (#232690)
Add tests for loops with uncountable early exits that contain
reductions, including reductions and reduction phis used on the early
exits.
Also keep the first loop in create-induction-resume.ll scalar, so the
test keeps exercising the IV expansion once early-exit loops with
reductions can be vectorized.
fix: [CIR] Check only the converted pointer's address space
Limit opaque pointer conversion to its own address space and diagnose unsupported pointee types where their layout is required. Emit type-specific errors for failed pointer conversions.
Validate pointee memory conversion before deriving copy sizes, alignments, or pointer-difference strides from CIR layout. Keep deeper pointee types opaque when their layouts are not needed.

py-jedi: updated to 0.20.1
0.20.1
- Avoid loading an executable path from `project.json`
- Avoid changing the global recursion limit
- Support for async pytest fixtures
- Work better with PEP 695 type parameter syntax
[CIR] Reject language address spaces in DirectToLLVM pointer conversion
Reject unlowered language address spaces in pointer types when bypassing TargetLowering. Guard pointer-producing lowerings, including generated patterns, so failed conversions report legalization failures instead of silently selecting address space zero or constructing invalid LLVM operations.

[CIR] Propagate initializer type adjustment failures
