[AMDGPU]: Add implicit-def to the BB prolog (#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.
