[PowerPC] Fix instruction sizes / branch relaxation (#175556)
For PowerPC, having accurate (or at least not too small) instruction
sizes is critical, because the PPCBranchSelector pass relies on them.
Underestimating the size of an instruction can result in the wrong
branch kind being chosen, which will result in an MC error.
This patch introduces validation that the instruction size reported by
TII matches the actually emitted instruction size, and fixes various
cases where this was not the case.
Fixes https://github.com/llvm/llvm-project/issues/175190.
[mlir][Utils] Add verifyElementTypesMatch helper (NFC) (#176668)
This change builds on #174336 and #175880, which introduced shared
VerificationUtils with verifyDynamicDimensionCount() and
verifyRanksMatch() methods.
This patch adds a new verifyElementTypesMatch() verification utility
that checks if two shaped types have matching element types and emits
consistent error messages. The utility is applied to several ops across
the MemRef and Vector dialects.
[MLIR][OpenMP] Simplify OpenMP device codegen
After removing host operations from the device MLIR module, it is no longer
necessary to provide special codegen logic to prevent these operations from
causing compiler crashes or miscompilations.
This patch removes these now unnecessary code paths to simplify codegen logic.
Some MLIR tests are now replaced with Flang tests, since the responsibility of
dealing with host operations has been moved earlier in the compilation flow.
MLIR tests holding target device modules are updated to no longer include now
unsupported host operations.

[VectorCombine] Fold vector sign-bit checks (#175194)
Fold patterns that extract sign bits, reduce them, and compare against
boundary values into direct sign checks on the reduced vector.
```
icmp pred (reduce.{add,or,and,umax,umin}(lshr X, BitWidth-1)), C
-> icmp slt/sgt (reduce.{or,umax,and,umin}(X)), 0/-1
```
When the comparison is against 0 or MAX (1 for boolean reductions,
NumElts for add), the pattern reduces to one of four quantified
predicates:
- ∀x: x < 0 (AllNeg)
- ∀x: x ≥ 0 (AllNonNeg)
- ∃x: x < 0 (AnyNeg)
- ∃x: x ≥ 0 (AnyNonNeg)
The transform eliminates the shift and selects between

since during initial HA setup our node will be SINGLE on

[DSE] Make DSE eliminate stores to objects with a sized dead_on_return
dead_on_return is made optionally sized in #171712. This patch adds
handling in DSE so that we can actually eliminate stores to pointer
parameters marked with a sized dead_on_return attribute. We do not
eliminate stores where the store may overlap with bytes that are not
known to be dead after return.
