[AMDGPU]: Add implicit-def to the BB prolog (llvm#112872)
IMPLICIT_DEF inserted for a wwm-register at the very first block or the predecessor block where it is used for sgpr spilling can appear at a block begin that requires spill-insertion during per-lane VGPR regalloc phase. The presence of the IMPLICIT_DEF currently breaks the BB prolog. Fixes: SWDEV-490717 Change-Id: I16793e338851a4d5a3ac90807afb11816d527bea
