ed01ee03 - ccall: handle Union appearing as a field-type without crashing (#46787)

ccall: handle Union appearing as a field-type without crashing (#46787) We disallow union as the direct type, so perhaps we should disallow it as a field-type also, but since we do allow references in those cases typically, we will allow this also. Also DRY the emit_global code, since it had bit-rotted relative to the usual code path through emit_globalref (and apparently could still be run though for handling the first argument to cfunction). Fix #46786
