AMDGPU/GlobalISel: add RegBankLegalize rules for AND OR and XOR (#132382)
Uniform S1 is lowered to S32. Divergent S1 is selected as VCC(S1) instruction select will select SALU instruction based on wavesize (S32 or S64). S16 are selected as is. There are register classes for vgpr S16. Since some isel patterns check for sgpr S16 we don't lower to S32. For 32 and 64 bit types we use B32/B64 rules that cover scalar vector and pointers types. SALU B32 and B64 and VALU B32 instructions are available. Divergent B64 is lowered to B32.
