d: Fix internal compiler error: Segmentation fault at gimple-expr.cc:88

Because complex types are deprecated in the language, the new way to
expose native complex types is by defining an enum with a basetype of a
library-defined struct that is implicitly treated as-if it is native.
As casts are not implicitly added by the front-end when downcasting from
enum to its underlying type, we must insert an explicit cast during the
code generation pass.

	PR d/106623

	library-defined equivalent.
	* d-tree.h (underlying_complex_expr): Declare.
	* expr.cc (ExprVisitor::visit (DotVarExp *)): Call
	underlying_complex_expr instead of build_vconvert.
