[SanitizerCoverage] Add associated metadata to 8-bit counters.

Summary:
This allows counters associated with unused functions to be
dead-stripped along with their functions.  This approach is the same one
we used for PC tables.

Fixes an issue where LLD removes an unused PC table but leaves the 8-bit
counter.
