This patch adds a new '-fdump-front-end' flag and associated dump
machinery. I use it on the modules branch, as that's sufficiently
complex to need a dumper. The dump file is unnumbered with a '.fe'
suffix. Perhaps it will be useful for other front ends too.
I'm also prepared to remove the -fdump-translation-unit dumper, which is
a completely inscrutable c++ only dump, that I think is well past its
best-before date. (Jason?)
If there's a preference to hold this off until merging modules, that's
fine. Just thought I'd float it now.
