[BOLT] Use regex matching for function names passed on command line

Summary:
Options such as `-print-only`, `-skip-funcs`, etc. now take regular
expressions. Internally, the option is converted to '^funcname$' form
prior to regex matching. This ensures that names without special
symbols will match exactly, i.e. "foo" will not match "foo123".
