Don't accidentally detect the commit hash as an fadd instruction #116591

I've seen some reports of tests/codegen/target-feature-inline-closure.rs spuriously failing because it thinks the hash in the rustc version number contains an fadd instruction.

This PR tries to make that not happen by adding a CHECK-LABEL directive that will match the line with the rustc version string, preventing the previous CHECK-NOT from seeing it.

There may be a more principled or universal way to achieve this, so I'm open to suggestions.

It's a little hard to properly test that this change actually works (especially since I'm not even on x86_64), but locally I did rig up another test to deliberately fail in a similar way, and this does seem to do the trick.
