[clang] Add CHECK-LABEL to avoid source tree path sensitivity in test (PR #112461)

[Tex Riddell via cfe-commits]

https://github.com/tex3d created https://github.com/llvm/llvm-project/pull/112461

The test `clang/test/CodeGen/2004-02-20-Builtins.c` will erroneously fail if "builtin" is in the path to your source tree.

This change adds a `CHECK-LABEL !llvm.ident` after the `CHECK-NOT` to avoid searching into the metadata containing the path.
