[COMMITTED 099/220] gccrs: nr2.0: Fix resolution of constant items

[arthur . cohen]

From: Owen Avery <powerboat9.ga...@gmail.com>

gcc/rust/ChangeLog:

        * resolve/rust-default-resolver.cc (DefaultResolver::visit):
        Call DefaultASTVisitor::visit even on ConstantItem instances
        without expressions.

gcc/testsuite/ChangeLog:

        * rust/compile/nr2/exclude: Remove issue-3642.rs.
