These options are taking regex separated by colons to filter files.

- if both are empty then all files are instrumented
- if -coverage-filter is empty then all the filenames matching any of the regex from exclude are not instrumented
- if -coverage-exclude is empty then all the filenames matching any of the regex from filter are instrumented
- if both aren't empty then all the filenames which match any of the regex in filter and which don't match all the regex in filter are instrumented
- this patch is a follow-up of https://reviews.llvm.org/D52033
