Pratyai Mazumder e8d1c6529b [SanitizerCoverage] sancov/inline-bool-flag instrumentation. ...

Summary:
New SanitizerCoverage feature `inline-bool-flag` which inserts an
atomic store of `1` to a boolean (which is an 8bit integer in
practice) flag on every instrumented edge.

Implementation-wise it's very similar to `inline-8bit-counters`
features. So, much of wiring and test just follows the same pattern.
