RFC: [GUPC] UPC-related changes

[Gary Funck]

FYI, over the course of the next week/so, I will
post UPC-related changes to the gcc-patches
mailing list, for review.  The goal is to make the
necessary fixes/changes, based upon review feedback,
that need to be made prior to merging the GUPC branch
into the GCC trunk.

Email describing the changes will be grouped according to
a general area (front-end, make/configure,
debugging info., middle-end, etc.). The first email,
describing front-end changes is here:
