Some unused variables caused a build failure of c6x-* with
config-list.mk. It seems these variables have been unused from the
outset, so they're probably left over from a pre-submission version
of the code.
Tested with config-list.mk and pushed as obvious.

* config/c6x/c6x.cc (reorg_split_calls): Remove unused uid
and reservation_mask variables.
(hwloop_optimize): Remove unused delayed_splits variable.
