Remove regular visit code

Regular visit code can be replaced with default visit functions.

gcc/rust/ChangeLog:

	* resolve/rust-default-resolver.cc (DefaultResolver::visit): Remove
	default visit code and replace it with call to default visitor.
	* resolve/rust-default-resolver.h: Remove removed function's
	prototypes.
