This patch adds LLVM intrinsics for the `dcbt` (Data Cache Block Touch),
`dcbtst` (Data Cache Block Touch for Store) and `isync` (Instruction
Synchronize) instructions.

The intrinsic for dcbt and dcbst in this patch are named llvm.ppc.dcbt.with.hint
and llvm.ppc.dcbtst.with.hint respectively as there already exists an intrinsic
for llvm.ppc.dcbt and llvm.ppc.dcbtst. However, the original variants of the
intrinsics do not accept the TH immediate field, whereas these variants do.
