Diana Picus 09c41246ed [AMDGPU] Fix restores in chain functions (#116193) ...

When spilling a VGPR in `emitPrologue`, chain functions prefer to use
offsets to access the stack instead of the SP.

This patch fixes `emitEpilogue` to do the same. It also brings back some
test coverage that was lost in #93526, when WWM registers started being
shifted to the lowest available range (which meant that tests that were
originally spilling v8 would shift to spill v0, which is a scratch
register for chain functions and didn't get spilled).
