AMDGPU/SI: Use flat for global load/store when targeting HSA Summary: For some reason doing executing an MUBUF instruction with the addr64 bit set and a zero base pointer in the resource descriptor causes the memory operation to be dropped when the shader is executed using the HSA runtime. This kind of MUBUF instruction is commonly used when the pointer is stored in VGPRs. The base pointer field in the resource descriptor is set to zero and and the pointer is stored in the vaddr field. This patch resolves the issue by only using flat instructions for global memory operations when targeting HSA. This is an overly conservative fix as all other configurations of MUBUF instructions appear to work.

AMDGPU: Set flat_scratch from flat_scratch_init reg This was hardcoded to the static private size, but this would be missing the offset and additional size for someday when we have dynamic sizing. Also stops always initializing flat_scratch even when unused. In the future we should stop emitting this unless flat instructions are used to access private memory. For example this will initialize it almost always on VI because flat is used for global access. llvm-svn: 260658

AMDGPU: Rework how private buffer passed for HSA If we know we have stack objects, we reserve the registers that the private buffer resource and wave offset are passed and use them directly. If not, reserve the last 5 SGPRs just in case we need to spill. After register allocation, try to pick the next available registers instead of the last SGPRs, and then insert copies from the inputs to the reserved registers in the progloue. This also only selectively enables all of the input registers which are really required instead of always enabling them. llvm-svn: 254331
