There was a problem hiding this comment.
There's a Type Call is not generic error on the input here, so the output is fairly flexible. Preserving the erroneous input node is fine, since it's what isolatedDeclarations wants.

Fixes #58430
Like #58428, this takes a case where the checker usually issues an error and blocks declaration emit and adjusts the output to match what
isolatedDeclarationusers expect - retaining the input type node (note that I've flagged this behind the flag I added in #58428 (and renamed that flag to be a bit more general) so error messages will still printanyinstead of whatever node produced the error).I actually had this change in one of my older omnibus node builder improvement PRs, but it got lost when I was breaking things up to be more reviewable.
