[AMDGPU] Switch address space mapping by triple environment amdgiz For target environment amdgiz and amdgizcl (giz means Generic Is Zero), AMDGPU will use new address space mapping where generic address space is 0 and private address space is 5. The data layout is also changed correspondingly. Differential Revision: https://reviews.llvm.org/D31210 llvm-svn: 298767

[AMDGPU] - Add address space for strided buffers (#74471) This is an experimental address space for strided buffers. These buffers can have structs as elements and a stride > 1. These pointers allow the indexed access in units of stride, i.e., they point at `buffer[index * stride]`. Thus, we can use the `idxen` modifier for buffer loads. We assign address space 9 to 192-bit buffer pointers which contain a 128-bit descriptor, a 32-bit offset and a 32-bit index. Essentially, they are fat buffer pointers with an additional 32-bit index.
