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
