Instead of using a low-level `is_ident` that only works on ascii characters. Instead match directly on the '_' character. The original functionality has been restored (using `isAlpha` instead). This commit removes the now unneccessary `is_ident` compat layer

I think that it makes sense to add a simple test based on the repro I reported in #2859 to make sure that the reported issue is actually solved by this PR. |

Will add one yes |

Regression test properly fails. Will timeout after some time, hope this is reasonable? |

Closes #2859

For redundant import actions, the code path ends up calling
wrapOperatorInParenwhich under the hood makes a call tois_identwhich is a low-levelChar -> Bool. The function will panic when it's input falls out of ASCII range.The fix is just to match directly on the '_' character. Outside of this codepath, the original
functionality has been restored (using
isAlpha).Also removes the now unnecessary
is_identcompat layer.
