[PATCH] remove redundant degenerate() in compatible_assignment_types()

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

In compatible_assignment_types(), the source expression is
first degenerated before calling check_assignment_types().

But this is not needed since check_assignment_types() must
anyway do the call to degenerate().

So, remove the redundant call to degenerate().
