[ProfCheck][Matrix] Add profile data where relevant
This patch tackles two cases:
1. Checks around aliasing/overlapping ranges. This is runtime dependent
on the pointer values passed in, which we have no way of knowing
without additional profiling.
2. Loop backedges. For these we also have an associated trip count, so
we set up the branch weights to represent this.
Tests updated/profcheck-xfail.txt updated.

[NFC][Matrix] Make CreateLoop take ConstantInt for Bound/Step
These should always be constants (unless someday we add support for
scalable matrices and then we can revisit). Explicitly pass them as
ConstantInt so we can avoid needing to downcast in a future PR that will
calculate appropriate branch weights using these values.

[ProfCheck][Matrix] Propagate profile information for selects
LowerMatrixIntrinsics creates new selects in the process of lowering
matrix intrinsics. The condition of such selects remains the same as
before. Because of this, we can directly propagate the profile
information for all selects on scalar conditions.

[LangRef][ConstantTime] Add documentation for llvm.ct.select.* constant-time intrinsics (#181042)
This PR introduces and documents the llvm.ct.select.* constant-time
intrinsics, providing timing-independent selection operations for
security-sensitive code. The LangRef is updated with syntax, semantics,
supported types, and usage guidance.
Additionally, test coverage is extended with a new <8 x float> variant
(llvm.ct.select.v8f32) and corresponding X86 codegen tests to ensure
correct lowering on both x64 and x32 targets.
[CIR] Implement shouldCreateMemCpyFromGlobal in LoweringPrepare (#181276)
CIRGen emits cir.const + cir.store for aggregate initialization, keeping
closer to source-level semantics. LoweringPrepare transforms stores of
constant aggregates (arrays, records) into cir.global + cir.get_global +
cir.copy, matching OG codegen's shouldCreateMemCpyFromGlobal
optimization.
The transform only applies to stores targeting cir.alloca (local
variables inside cir.func). Stores in other contexts (e.g. OpenACC
reduction recipe init blocks, base class initialization) are left as
cir.const + cir.store.
Also fixes CopyOp lowering to use i64 for the memcpy length instead of
i32, matching OG codegen behavior.
[LLVM][Utils] Fix automerge in git-llvm-push (#181766)
Enabling automerge can only be done using the GraphQL API. Add in some
basic GraphQL infrastructure and update the enable_automerge method to
call the GraphQL API to enable automerge for a PR.
Tested locally on #181762.
Closes #181634.
[AArch64][llvm] Remove `+xs` gating for `tlbip *nxs` instructions
A recent specification update has removed FEAT_XS gating for `tlbip *nxs`
instructions. It remains gated on FEAT_XS for `tlbi *nxs` instructions.
[AArch64][llvm] Gate some `tlbip` insns with +tlbid or +d128
Change the gating of `tlbip` instructions containing `*E1IS*`, `*E1OS*`,
`*E2IS*` or `*E2OS*` to be used with `+tlbid` or `+d128`. This is because
the 2025 Armv9.7-A MemSys specification says:
```
All TLBIP *E1IS*, TLBIP*E1OS*, TLBIP*E2IS* and TLBIP*E2OS* instructions
that are currently dependent on FEAT_D128 are updated to be dependent
on FEAT_D128 or FEAT_TLBID
```
