gccrs: Remove empty visit functions

We can let the default visitor visit those nodes anyway so we're sure
all nodes can be reached.

gcc/rust/ChangeLog:

	* resolve/rust-default-resolver.cc (DefaultResolver::visit): Remove
	empty visit function implementations.
	* resolve/rust-default-resolver.h: Remove corresponding prototypes.
