[PATCH] rs6000: Fix PR67045

[PATCH] rs6000: Fix PR67045

[Segher Boessenkool]

Paper bag time.  Committing as obvious fix.  Bootstrapped and regression
checked on powerpc64-linux and powerpc64le-linux; also bootstrapped the
latter with --enable-checking=release and -O3 (the PR67045 case).  Will
do an --enable-checking=yes,rtl as well.

	PR target/66217
	PR target/67045
	* config/rs6000/rs6000.md (and<mode>3): Put a CONST_INT_P check
	around those cases that need one.
