Create new test system for name resolution 2.0

This runs the standard compile/*.rs tests
with name resolution 2.0 enabled. The exclude file
can be used to exclude tests which are not yet working
with name resolution 2.0.

gcc/testsuite/ChangeLog:

	* rust/compile/nr2/compile.exp: New test.
	* rust/compile/nr2/exclude: New.
