gcc.dg/ifcvt-4.c currently FAILs for 64-bit SPARC:
FAIL: gcc.dg/ifcvt-4.c scan-rtl-dump ce1 "2 true changes made"
Eric suggested in the PR that Jeff's fix for PR rtl-optimization/69942
to gcc.dg/ifcvt-5.c applies here as well and indeed it does.
While I was at it, I removed the superfluous default args to dg-skip-if,
which only hinder readibility. I should probably make a pass over the
whole testsuite to get rid of this nonesense once stage 1 opens.
Tested with the appropriate runtest invocations on sparc-sun-solaris2.12
and i386-pc-solaris2.12. Ok for mainline?

* gcc.dg/ifcvt-4.c: Use "word_mode" rather than "int" to limit the
effects of argument promotions.
Remove default args to dg-skip-if.
