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

Tue Sep 2 07:14:19 PDT 2025

https://github.com/MacDue created https://github.com/llvm/llvm-project/pull/156460

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.
