Allow empty struct expressions in Rust
I learned recently that empty struct expressions, like "X{}", have been
promoted from experimental to stable in Rust. This patch changes the
Rust expression parser to allow this case.
New test case included.
Built and regtested on x86-64 Fedora 23, using Rust 1.11 beta.

* rust-lang.c (rust_tuple_struct_type_p): Return false for empty
structs.
* rust-exp.y (struct_expr_list): Allow empty elements.
2016-07-21 Tom Tromey <tom@tromey.com>
* gdb.rust/simple.rs (main): Use empty struct expression.
* gdb.rust/simple.exp: Add tests for empty struct expression.
