[AArch64][GISel] Lower llvm.prefetch
This change adds support for lowering llvm.prefetch directly using
GlobalISel. Currently, llvm.prefetch falls back to SelectionDAG.
This Change:
- Adds an AArch64-specific G_PREFETCH generic instruction, to be used
where AArch64ISD::PREFETCH is used in SelectionDAG.
- Adds the GINodeEquiv so patterns are translated over to GlobalISel
automatically.
- Corrects the AArch64Prefetch patterns to use a target immediate, which
is needed to get the patterns to translate across correctly.
- Translates the SelectionDAG legalisation of the prefetch intrinsic
into the corresponding GlobalISel legalisation.
