This adds subtarget features for v8.7-A's limited-tlb-maintenance nXS
instruction qualifiers, for the WFET/WFIT instructions and for the
HCRX_EL2 system register, allowing each to be conditional on their own
SubtargetFeature instead of being conditional on the base "v8.7a" feature.

Based on patches written by Simon Tatham.
