Subject: Avoid -mno-accumulate-outgoing-args in tests on Windows target

The -mno-accumulate-outgoing-args option does not work with the stack
probing used on Windows targets, giving a warning and so causing tests
using that option to fail.  This patch makes three tests not use that
option on affected targets, like sse-10.c (see
<http://gcc.gnu.org/ml/gcc-patches/2008-03/msg00180.html> for the
introduction of the warning and the sse-10.c change).

Tested with cross to i686-mingw32.  OK to commit?

	gcc.target/i386/pr46226.c: Do not use
	-mno-accumulate-outgoing-args.
