clang-p2996/llvm/test/CodeGen/AMDGPU/GlobalISel/regbankselect-amdgcn.struct.ptr.buffer.load.ll
Petar Avramovic 87503fa51c Revert "AMDGPU/GlobalISel: Add stub custom regbankselect pass" (#113913) 
This reverts commit e9c49901a4.
Current AMDGPURegBankSelect does nothing different then RegBankSelect.
Revert to using generic RegBankSelect in preparation for adding new
regbankselect passes. New AMDGPURegBankSelect, that will use uniformity
analysis for regbank select decisions, will not subclass RegBankSelect.
Revert regression tests to use regbankselect since amdgpu-regbankselect
will be used by new pass and behavior will be different.
