AMDGPU/SI: Use v_readfirstlane to legalize SMRD with VGPR base pointer Summary: Instead of trying to replace SMRD instructions with a VGPR base pointer with an equivalent MUBUF instruction, we now copy the base pointer to SGPRs using v_readfirstlane. This is safe to do, because any load selected as an SMRD instruction has been proven to have a uniform base pointer, so each thread in the wave will have the same pointer value in VGPRs. This will fix some errors on VI from trying to replace SMRD instructions with addr64-enabled MUBUF instructions that don't exist.

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel Currently the default C calling convention functions are treated the same as compute kernels. Make this explicit so the default calling convention can be changed to a non-kernel. Converted with perl -pi -e 's/define void/define amdgpu_kernel void/' on the relevant test directories (and undoing in one place that actually wanted a non-kernel). llvm-svn: 298444
