Adds intrinsics for the following instructions:

- WHILEGE (predicate pair)
- WHILEGT (predicate pair)
- WHILEHI (predicate pair)
- WHILEHS (predicate pair)
- WHILELE (predicate pair)
- WHILELO (predicate pair)
- WHILELS (predicate pair)
- WHILELT (predicate pair)

I've added an opcode selector called SelectOpcodeFromVT to
AArch64ISelDAGToDAG.cpp that we will extend in future to
select opcodes from different MVTs. For now, the only use is
for selecting predicate types.

NOTE: These intrinsics are still in development and are subject
to future changes.
