Add CHECK-LABEL to avoid source tree path sensitivity in test

[tex3d]

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.

Could also consider checking for ret void instead, as that's more flexible if someone were to add another test case later in the file. This seems fine too though.
