[cfe-commits] [PATCH] Fix warnings found by gcc-4.6 (issue3888041)

The full patch is at
http://codereview.appspot.com/download/issue3888041_1.diff. Please take
a look.

Description:
Most of these were found by the new -Wunused-but-set-variable warning.
Several of these unused variables look like they ought to have been
used, so someone who knows this code better than I do should check
whether the new warnings found some bugs.

I also fixed some spurious -Wint-to-pointer-cast warnings.

I checked that everything was fixed with `make CFLAGS="-Werror"
CXXFLAGS="-Werror"`
