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

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.
