[Utils] Fix AArch64 ASM regex after #148287 (#156460)

MacDue · web-flow · commit 314dc33e4dcc · 2025-09-02T14:48:04.000Z
PR #148287 removed the "\s*" before ".Lfunc_end" for AArch64, which broke `update_llc_test_checks.py` for a number of tests including: - `llvm/test/CodeGen/AArch64/sme-za-exceptions.ll` - `llvm/test/CodeGen/AArch64/win-sve.ll` This patch adds the "\s*" back.
