* config/cris/cris.md ("*adddi3<setnz>"): Rename from "*adddi3".
cris: Enable 32-bit addition to set condition codes.
("*subdi3<setnz>"): Similarly from "*subdi3".
("*addsi3<setnz>"): Similarly from "*addsi3".
("*subsi3<setnz>"): Similarly from "*subsi3".
("*addhi3<setnz>"): Similarly from "*addhi3" and decorate the
"cc" attribute to "cc<ccnz>".
("*addqi3<setnz>"): Similarly from "*addqi3".
("*sub<mode>3<setnz>"): Similarly from "*sub<mode>3".
Enabling dropping of compares with zero of the result, through
the non-VC-setting CCmode substitution. Beware that the
substitutions for 8- and 16-bit patterns will in some cases be
size-neutral; e.g. replacing an "addq 1..63,$rN" + "test.w $rN"
or "subq 1..63,$rN" + "test.w $rN" with an "add.w -63..63,$rN".
