Given how close we are to gcc-15 release, disable it for now. Since we do want to retain and re-enable this capabilty, manully disable vs. reverting the orig patch which takes away the test case too. Fix the orig test case to expect old codegen idiom (although vneg is no longer emitted, in favor of vrsub). Also add a new testcase which flags any future spills in the affected routine.
