7800d59f - [SanitizerCoverage] Add gated tracing callbacks support to trace-cmp (#113227)

[SanitizerCoverage] Add gated tracing callbacks support to trace-cmp (#113227) The option -sanitizer-coverage-gated-trace-callbacks gates the invocation of the trace-pc-guard callbacks based on the value of a global variable, which is stored in a specific section. In this commit, we extend this feature to trace-cmp and gate the cmp callbacks to the same variable used for trace-pc-guard. Update SanitizerCoverage doc with this flag. rdar://135404160 Patch by: Andrea Fioraldi
