AMDGPU: Run internalize symbols at -O0 The relocations used for externally visible functions aren't supported, so the direct call emitted ends up hitting a linker error. llvm-svn: 313616

[AMDGPU] Internalize non-kernel symbols Since we have no call support and late linking we can produce code only for used symbols. This saves compilation time, size of the final executable, and size of any intermediate dumps. Run Internalize pass early in the opt pipeline followed by global DCE pass. To enable it RT can pass -amdgpu-internalize-symbols option. Differential Revision: https://reviews.llvm.org/D29214 llvm-svn: 293549
