Adrian Prantl 5956b6b226 Darwin: introduce a global override for debug prefix map entries ...

This patch adds a new Darwin Swift driver environment variable in the spirit of
RC_DEBUG_OPTIONS, called RC_DEBUG_PREFIX_MAP, which allows a meta build tool to
add one additional -fdebug-prefix-map entry without the knowledge of the build
system.
