[PATCH] D50483: [SanitizerCoverage] Add associated metadata to PC guards.

There are more instances of !associated metadata used in this file on targets other than ELF. I don't know how that works, they should not have any effect, and AFAIK in MachO it means that the counters can be freely discarded.

As I understood, the runtime library relies on the fact that when the linker constructs sections for pcguards and for counters, it does that in the same order. This is not guaranteed.
