Stanislav Mekhanoshin 33092194f2 [AMDGPU] Select AGPR in PHI operand legalization
If a PHI defines AGPR legalize its operands to AGPR.
At the moment we can get an AGPR PHI with VGPR operands.
I am not aware of any problems as it seems to be handled
gracefully in RA, but this is not right anyway.

It also slightly decreases VGPR pressure in some cases
because we do not have to a copy via VGPR.
