Matt Morehouse 0f22fac274 [SanitizerCoverage] Add associated metadata to PC guards. 
Summary:
Without this metadata LLD strips unused PC table entries
but won't strip unused guards.  This metadata also seems
to influence the linker to change the ordering in the PC
guard section to match that of the PC table section.

The libFuzzer runtime library depends on the ordering
of the PC table and PC guard sections being the same.  This
is not generally guaranteed, so we may need to redesign
PC tables/guards/counters in the future.
