3c8b644d0d Only check for errors in predicate when skipping impl assembly
Prior to PR #91205, checking for errors in the overall obligation
would check checking the `ParamEnv`, due to an incorrect
`super_visit_with` impl. With this bug fixed, we will now
bail out of impl candidate assembly if the `ParamEnv` contains
any error types.

In practice, this appears to be overly conservative - when an error
occurs early in compilation, we end up giving up early for some
predicates that we could have successfully evaluated without overflow.
By only checking for errors in the predicate itself, we avoid causing
additional spurious 'type annotations needed' errors after a 'real'
error has already occurred.

With this PR, the diagnostic changes caused by PR #91205 are reverted.

9274ec5691 Visit param_env field in Obligation's TypeFoldable impl
This oversight appears to have gone unnoticed for a long time
without causing issues, but it should still be fixed.
