Jay Foad 86f2e09250 [AMDGPU] Tweak handling of GlobalAddress operands in SI_PC_ADD_REL_OFFSET (#70960) ...

When SI_PC_ADD_REL_OFFSET is expanded to S_GETPC/S_ADD/S_ADDC, the
GlobalAddress operands have to be adjusted by 4 or 12 bytes to account
for the offset from the end of the S_GETPC instruction to the literal
operands. Do this all in SIInstrInfo::expandPostRAPseudo instead of
duplicating the adjustment code in both AMDGPULegalizerInfo and
SITargetLowering. NFCI.
