Herald added a project: LLVM.
pcc added a child revision: D65770: hwasan: Instrument globals..

Any addresses that we pass to llvm-symbolizer are going to be untagged,
while any HWASAN instrumented globals are going to be tagged in the
symbol table. Therefore we need to untag the addresses before using them.
