[PATCH 079/125] gccrs: Add tuple struct constructor to value namespace

[Arthur Cohen]

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

A tuple struct constructor should be inserted in the value namespace
during name resolution in order to reject multiple definitions of the
function.

gcc/rust/ChangeLog:

        * resolve/rust-toplevel-name-resolver-2.0.cc (TopLevel::visit): Add
        the struct constructor to the value namespace.

gcc/testsuite/ChangeLog:

        * rust/compile/name_resolution22.rs: New test.
