[COMMITTED 061/101] gccrs: Add execution test for name resolution 2.0

[arthur.cohen@embecosm.com]

From: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>

We already have some compile tests but it lacked an execution test to
ensure everything compiles correctly to the correct value.

gcc/testsuite/ChangeLog:

	* rust/execute/torture/name_resolution.rs: New test.
