Load unloaded modules during toplevel resolution 2.0

This may load conditionally compiled modules too eagerly.

gcc/rust/ChangeLog:

	* resolve/rust-toplevel-name-resolver-2.0.cc
	(TopLevel::visit): Load unloaded modules before attempting to
	visit their items.

gcc/testsuite/ChangeLog:

	* rust/compile/nr2/exclude: Remove issue-1089.rs.
