[PATCH] Remove unused variables found by gcc-4.6's -Wunused-but-set-variable

Some of these removals may actually indicate bugs, so someone who knows this code better than I do should take a look.

There are a couple other gcc-4.6 warnings in googletest, but we should get a fix for them when they release version 1.6.

Those unused in the CellSPU target are OK to remove.
