  -----------
  [flang] Silence spurious errors from benign USE errors (#106097)

When USE association encounters a conflict that can't be resolved, it
produces a "UseError" symbol that will trigger an error message if that
symbol is ever actually used. UseError symbols that aren't used are
benign.

Ensure that UseError symbols don't run the gamut of declaration
checking. They were getting through, and could lead to spurious error
messages.

Fixes https://github.com/llvm/llvm-project/issues/106020.
