[PATCH] D156413: [AMDGPU][PEI] Set up SP for chain functions

[Diana Picus via Phabricator via llvm-commits]

Use requiresStackPointerReference. We still need to check hasStackObjects though, otherwise we end up using an uninitialized s32 for spills and allocas. Ideally we'd be able to use an immediate for those cases, but I haven't figured out how to do that yet, so I left a FIXME.
