Re-commit AMDGPU/GlobalISel: Add support for simple shaders Fix build when global-isel is disabled and fix a warning. Summary: We can select constant/global G_LOAD, global G_STORE, and G_GEP.

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

[GlobalISel] Don't select trivially dead instructions. Folding instructions when selecting can cause them to become dead. Don't select these dead instructions (if they don't have other side effects, and don't define physical registers). Preserve existing tests by adding COPYs. In some tests, the G_CONSTANT vregs never get constrained to a class: the only use of the vreg was folded into another instruction, so the G_CONSTANT, now dead, never gets selected. llvm-svn: 298224
