Subject: [PATCH 2/2] AMDGPU/GlobalISel: uniformity analysis based register
bank selection
Current algorithm only considers register banks for inputs but does
take control flow into account.
This is wrong in cases where inputs are uniform (in sgpr) but because
of divergent control flow instruction is divergent and should use vgpr
instead of sgpr register banks. Most notable example are phis.
Also in cases where only available machine instruction uses vgpr
registers uniform instructions end up using vgpr register banks.
Start with simple implementation for G_FADD.
Pre-select register bank for destination register using machine
uniformity analysis info. Then select register banks that would allow
selection of available machine instructions.
For G_FADD vgpr machine instruction is available on all targets but
sgpr version is not. When there is no sgpr version assign vgpr register
banks and move vgpr destination to sgpr using readfirstlane.
