Matt Morehouse 3bea25e554 [SanitizerCoverage] Create comdat for global arrays. 
Summary:
Place global arrays in comdat sections with their associated functions.
This makes sure they are stripped along with the functions they
reference, even on the BFD linker.

This reverts r341987 since it will cause trouble when there's a module
ID collision.
