[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.

The LLVM Compiler Infrastructure

This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments.
