  1. [SimplifyCFG] Skip sinking common lifetime markers of alloca. 

    Summary:
- Similar to the workaround in fix of PR30188, skip sinking common
  lifetime markers of `alloca`. They are mostly left there after
  inlining functions in branches.

  2. [AArch64][GlobalISel] Select @llvm.aarch64.ldaxr.* intrinsics 

    Add a GISelPredicateCode to ldaxr_*. This allows us to import the patterns for
@llvm.aarch64.ldaxr.*, and thus select them.

Add `isLoadStoreOfNumBytes` for the GISelPredicateCode, since each of these
intrinsics involves the same check.

Add select-ldaxr-intrin.mir, and update arm64-ldxr-stxr.ll.

  3. [AArch64][GlobalISel] Select @llvm.aarch64.ldxr.* intrinsics 

    Same thing as D66897, but for ldxr.* instead. Add a GISelPredicateCode to the
ldxr_* definitions, which allows us to import them.

Add select-ldxr-intrin.mir, and update arm64-ldxr-stxr.ll.

  5. [GlobalISel][AArch64] Use a GISelPredicateCode to select llvm.aarch64… 

    ….stlxr.*

Remove manual selection code for this intrinsic and use a GISelPredicateCode
instead.

This allows us to fully select this intrinsic without any tricky custom C++
matching.
