Christudasan Devadasan ce7fd498ed [AMDGPU] RA inserted scalar instructions can be at the BB top (#72140) ...

We adjust the insertion point at the BB top for spills/copies during RA
to ensure they are placed after the exec restore instructions required
for the divergent control flow execution. This is, however, required
only for the vector operations. The insertions for scalar registers can
still go to the BB top.
