gccrs: Adjust HIR dump for IfExpr and IfExprConseqElse

Adjust the HIR dump for IfExpr and IfExprConseqElse
to use visit_field() and factor common part.

gcc/rust/ChangeLog:

	* hir/rust-hir-dump.h (do_ifexpr): New.
	* hir/rust-hir-dump.cc (Dump::do_ifexpr): New.
	(Dump::visit): Use do_ifexpr and visit_field
