rs6000: Fix pr69946.c testcase (PR85126)

After middle-end changes combine now gets fed different input, from
which it makes different (but just as efficient) code.  So remove the
test for particular asm output.


gcc/testsuite/
	PR target/85126
	* gcc.target/powerpc/pr69946: Adjust comment.  Remove
	scan-assembler-times clause.
