Tim Keith a0858885c2 [flang] Recognize complex-part-designator
The "%RE" or "%IM" is parsed as a structure-component.
If the base has type COMPLEX and the component name is one
of those, allow it without comment.

Note that the `parser::Name` for these components don't get
symbols filled in, so we still get a warning that they are
unresolved. We have to figure out how to deal with names
like this that we won't have symbols for.

Fixes flang-compiler/f18#188.
