Jonathan Metzman 0b94e88007 [SanitizerCoverage] Prevent /OPT:REF from stripping constructors 
Summary:
Linking with the /OPT:REF linker flag when building COFF files causes
the linker to strip SanitizerCoverage's constructors. Prevent this by
giving the constructors WeakODR linkage and by passing the linker a
directive to include sancov.module_ctor.

Include a test in compiler-rt to verify libFuzzer can be linked using
/OPT:REF
