ARC support has been removed for GCC 4.7, but please ping patches such as this
to generic code if you think they are logically right (even if the issues are
latent for other targets).

Another testcase for ARC700 is: gcc.c-torture/execute/builtin-bitops-1.c -O1

Sorry, that's a mixup: the above is a testcase of an analogous bug in
rtlanal.c:dead_or_set_regno_p .
Note that the policy for ambiguous codes like POST_INC, ZERO_EXTRACT or
COND_EXEC of mark_set_resources is different from dead_or_set_p:
while the former errs on the side of marking something set, the latter
(is suspposed to) err(s) on the side of something not entirely killed.
