Christudasan Devadasan b25b4c0ab4 [AMDGPU] Separate out SGPR spills to VGPR lanes during PEI ...

SILowerSGPRSpills pass handles the lowering of SGPR spills
into VGPR lanes. Some SGPR spills are handled later during
PEI. There is a common function used in both places to find
the free VGPR lane. This patch eliminates that dependency to
find the free VGPR by handling it separately for PEI. It is a
prerequisite patch for a future work to allow SGPR spills to
virtual VGPR lanes during SILowerSGPRSpills.
