Typo spotted while doing CCmode improvements, as a missed
optimization. It's almost visible from the patch context;
there's not much done in terms of "mode-adjustment" when
replacing (reg:CC CRIS_CC0_REGNUM) with a copy!
This bug affects functions in the newlib printf-formatting
functions (nothing else in libgcc or newlib libc), with the
performance impact on coremark scores being less than 1e-6
(3/5078992 cycles, 6/48543 bytes).
* config/cris/cris.cc (cris_postdbr_cmpelim): Correct mode
of modeadjusted_dccr.
