cris: Correct output templates in define_subst patterns.
Whoops. This little gem had the effect of making the output
operand (0) constraints disappear but not the input operand (1)
constraints for define_subst:ed patterns, probably because
there's another (match_dup 1) in the output template (not
investigated).
That went surprisingly unnoticed until I added a pass leaning
just a little bit harder on the define_subst:ed patterns and
then only by the libgfortran library generating assembly with
nominally incorrect syntax. (There was a move to a special
register from a general register, and it incorrectly matched a
pattern affecting condition codes.)
gcc:
* config/cris/cris.md ("setnz_subst", "setnz_subst", "setcc_subst"):
Use match_dup in output template, not match_operand.
