Revert "InstrProf: Add unit tests for the profile reader and writer"

This added API to the InstrProfWriter to write to a string so I could
write unittests without using temp files. This doesn't really work,
since the format has tighter alignment requirements than a char.

This reverts r229478 and its follow-up, r229481.
