[SanitizerCoverage] Add associated metadata to pc-tables.
Summary:
Using associated metadata rather than llvm.used allows linkers to
perform dead stripping with -fsanitize-coverage=pc-table. Unfortunately
in my local tests, LLD was the only linker that made use of this metadata.
Partially addresses https://bugs.llvm.org/show_bug.cgi?id=34636 and fixes
https://github.com/google/sanitizers/issues/971.
