Justin Bogner 42ab8c0a90 InstrProf: Treat functions with a coverage map but no profile as unreached ...

If we have a coverage mapping but no profile data for a function,
calling it mismatched is misleading. This can just as easily be
unreachable code that was stripped from the binary. Instead, treat
these the same as functions where we have an explicit "zero" coverage
map by setting the count to zero for each mapped region.
