It seems the new expander triggers a latent issue in sched1 causing

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

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
