[COMMITTED 19/32] gccrs: Visit loop label before predicate expression

[arthur . cohen]

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

If the label is referenced within the while predicate expression it has
to be resolved before the latter.

gcc/rust/ChangeLog:

        * ast/rust-ast-visitor.cc (DefaultASTVisitor::visit): Change default
        visit order.

gcc/testsuite/ChangeLog:

        * rust/compile/nr2/exclude: Remove test from exclusion list.
