Subject: collector: Remove external container

The token collector was using an external container but it was later
revealed that this whole reuse thing was not necessary.

gcc/rust/ChangeLog:

	* ast/rust-ast-collector.cc (TokenCollector::TokenCollector):
	Remove constructor, changing it to an implicit default
	constructor.
	* ast/rust-ast-collector.h: Change from container reference to
	direct container.
	* ast/rust-ast-dump.h: Change call to constructor.
	* expand/rust-macro-expand.h (struct MacroExpander): Likewise.
