perf tool: Fix gcc 4.6.0 issues
GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf
due to the -Werror=unused-but-set-variable flag.
I've gone through and annotated some of the assignments that had side
effects (ie: return value from a function) with the __used annotation,
and in some cases, just removed unused code.
In a few cases, we were assigning something useful, but not using it in
later parts of the function.

[ committer note: Fixed up the annotation fixes, as that code moved recently ]
