[llvm-branch-commits] [llvm] release/23.x: Revert "[AArch64] Enable Spillage Copy Elimination by default" (#211572) (PR #211758)

Approving — straightforward revert of a problematic default-on codegen pass (Spillage Copy Elimination), restoring prior AArch64 behavior. Low risk, and @davemgreen (the area maintainer) already gave it an LGTM above.
