gccrs: Fix ICE with empty generic arguments

We have an assertion when accessing generic args if there are any which
is really useful so this adds the missing guards for the case where
they are specified but empty.

Fixes Rust-GCC#3649

gcc/rust/ChangeLog:

* ast/rust-ast-visitor.cc (DefaultASTVisitor::visit): add guard
* expand/rust-expand-visitor.cc (ExpandVisitor::visit): add guard

gcc/testsuite/ChangeLog:

* rust/compile/nr2/exclude: nr2 is missing error for this
* rust/compile/issue-3649.rs: New test.
