[APX CCMP] Use ctestcc when comparing to const 0
For CTEST, we don't have conditional AND so there's no optimization
opportunity to write a new ctest pattern. Emit ctest when ccmp did
comparison to const 0 to save bytes.
gcc/ChangeLog:
* config/i386/i386.md (@ccmp<mode>): Add new alternative
<r>,C and adjust output templates. Also adjust UNSPEC mode
to CCmode.
gcc/testsuite/ChangeLog:
* gcc.target/i386/apx-ccmp-1.c: Adjust output to scan ctest.
* gcc.target/i386/apx-ccmp-2.c: Adjust some condition to
compare with 0.
