[COMMITTED 120/141] gccrs: Add a test for enum variant name resolution

[arthur . cohen]

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

Highlight the fact that a value inside an enum definition refers to
a struct outside of the enum and not to the enum variant's name
directly.

gcc/testsuite/ChangeLog:

        * rust/compile/enum_variant_name.rs: New test.
