In Continuous instrumentation profiling mode, profile or coverage data collected via compiler instrumentation is continuously synced to the profile file. This feature has existed for a while, and is documented here: https://clang.llvm.org/docs/SourceBasedCodeCoverage.html#running-the-instrumented-program This PR creates a user facing option to enable the feature. --------- Co-authored-by: Wael Yehia <wyehia@ca.ibm.com>
