regcomp.h - document RE_PESSIMISTIC_PARENS and VOLATILE_REF defines
These two defines are related to each other, and even though
VOLATILE_REF is not explicitly used in regexec.c which would require
it being placed in regcomp.h, it is implicitly, and RE_PESSIMISTIC_PARENS
*is* used in regexec.c. So put them both in regcomp.h and document them
together. This adds copious documentation for what they both are for.
RE_PESSIMISTIC_PARENS is effectively a "build option" (although intended
for debugging regex engine bugs only). VOLATILE_REF is the name of a
flag which is used to mark REF nodes as requiring special backtracking
support in regexec.c
