Now that we have the sanitizer metadata that is actually on the global variable, and now that we use debuginfo in order to do symbolization of globals, we can delete the 'llvm.asan.globals' IR synthesis. This patch deletes the 'location' part of the __asan_global that's embedded in the binary as well, because it's unnecessary. This saves about ~1.7% of the optimised non-debug with-asserts clang binary. Reviewed By: vitalybuka Differential Revision: https://reviews.llvm.org/D127911
