[testsuite] [x86] no-callee-saved-16.c needs -fomit-frame-pointer

If the toolchain is built with --enable-frame-pointer,
gcc.target/i386/no-callee-saved-16.c will not get the expected
optimization without -fomit-frame-pointer, that would be enabled by
-O2 without the configure flag.  Add it.

for  gcc/testsuite/ChangeLog

	* gcc.target/i386/no-callee-saved-16.c: Add -fomit-frame-pointer.
