[AMDGPU] Add a pass to promote bitcast calls AMDGPU currently only supports direct calls, but at lower optimisation levels it fails to lower statically direct calls which appear indirect due to a bitcast. Add a pass to visit all CallSites and use CallPromotionUtils to "devirtualize" calls. Differential Revision: https://reviews.llvm.org/D52741 llvm-svn: 345382

AMDGPU: Remove error on calls for amdgcn Repurpose the -amdgpu-function-calls flag. Rather than require it to emit a call, only use it to run the always inline path or not. llvm-svn: 310003

AMDGPU: Fix crash if called function is a bitcast getCalledFunction() is null, so this would crash. Replace crash with an error on unsupported call. llvm-svn: 243461

[AMDGPU] Switch to the new addr space mapping by default This requires corresponding clang change. Differential Revision: https://reviews.llvm.org/D40955 llvm-svn: 324101
