Don't emit coverage mapping for excluded functions
When a function or a file is excluded using -fprofile-list= option,
don't emit coverage mapping as doing so confuses users since those
functions would always have zero count. This also reduces the binary
size considerably in cases where only a few functions or files are
being instrumented.
