Matt Arsenault 623e6fd466 AMDGPU: Hack for VS_32 register pressure ...

For some reason VS_32 ends up factoring into the pressure heuristics
even though we should never see a virtual register with this class.

When SGPRs are reserved for register spilling, this for some reason
triggers reg-crit scheduling.

Setting isAllocatable = 0 may help with this since that seems to remove
it from the default implementation's generated table.
