AMDGPU: Remove some uses of llvm.SI.export in tests Merge some of the old, smaller tests into more complete versions. llvm-svn: 295792

AMDGPU/SI: Make sure MIMG descriptors and samplers stay in SGPRs Summary: It's possible to have resource descriptors and samplers stored in VGPRs, either by a VMEM instruction or in the case of samplers, floating-point calculations. When this happens, we need to use v_readfirstlane to copy these values back to sgprs.

; FIXME: Move this to sgpr-copy.ll when this is fixed on VI.
; Make sure that when we split an smrd instruction in order to move it to
; the VALU, we are also moving its users to the VALU.

AMDGPU: Convert test cases to the dimension-aware intrinsics Summary: Also explicitly port over some tests in llvm.amdgcn.image.* that were missing. Some tests are removed because they no longer apply (i.e. explicitly testing building an address vector via insertelement). This is in preparation for the eventual removal of the old-style intrinsics. Some additional notes: - constant-address-space-32bit.ll: change some GCN-NEXT to GCN because the instruction schedule was subtly altered - insert_vector_elt.ll: the old test didn't actually test anything, because %tmp1 was not used; remove the load, because it doesn't work (Because of the amdgpu_ps calling convention? In any case, it's orthogonal to what the test claims to be testing.)
