Treat a consecutive semicolons in a prototype as 1

This also intentionally ignores spaces; they're ignored by

Show intflags as well as extflags
Fix and add tests for *PRUNE/*THEN plus leading non-greedy +

"aaabc" should match /a+?(*THEN)bc/ with "abc".
add PL_reg_intflags_name to globvar.sym - used in debugging regex engine
