	PR fortran/88116
	PR fortran/88467
	* array.c (gfc_match_array_constructor): Check return value of
	gfc_convert_type().  Skip constructor elements with BT_UNKNOWN,
	which need to go through resolution.
	* intrinsic.c (gfc_convert_type_warn): Return early if the types
	martch (i.e., no conversion is required).
	* simplify.c (gfc_convert_constant): Remove a gfc_internal_error,
	and return gfc_bad_expr.
