Arthur Eubanks 76902079e4 [clang] Don't modify OptRemark if the argument is not relevant ...

A followup to D110201.

 For example, we'd set OptimizationRemarkMissed's Regex to '.*' when
encountering -Rpass. Normally this doesn't actually affect remarks we
emit because in clang::ProcessWarningOptions() we'll separately look at
all -R arguments and turn on/off corresponding diagnostic groups.
However, this is reproducible with -round-trip-args.
