  [llvm][stackmaps] Include pristine registers for liveness computation. (#90529)

Users of stackmaps and patchpoints need to add all pristine registers to
the
spill set, even so they don't need to be all preserved.

This fixes the liveness computation for stackmaps to include pristine
registers.

This fixes rdar://21228337.
