rtlanal: Fix bits/bytes confusion in set_noop_p (PR68814)
The meaning of ZERO_EXTRACT depends on BITS_BIG_ENDIAN, not on
BYTES_BIG_ENDIAN. This caused PR68814.
2015-12-11 Segher Boessenkool <segher@kernel.crashing.org>
PR rtl-optimization/68814
* rtlanal.c (set_noop_p): Use BITS_BIG_ENDIAN instead of
BYTES_BIG_ENDIAN.
