gollvm: add support -Rpass=<regex> and related options

Add suport for -Rpass=<regex>, -Rpass-missed=<regex>, and
-Rpass-analysis=<regex> command line options, to allow enabling of
optimization remarks. Adding "-Rpass=inline" (for example) can be a
very handy way to understand what is/is-not being done by the inliner
when your code is compiled.
