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.
This will be useful for dealing with vectors; regardless of our final solution
for the Index trait.

gdb/ChangeLog:
* rust-lang.c (rust_subscript): Allow subscripting pointers
gdb/testsuite/ChangeLog:
* simple.rs: Add test for raw pointer subscripting
* simple.exp: Add test expectations
Rust prefers to not specify the return type of a function when it is unit
(`()`). The type is also referred to as "void" in debuginfo but not in actual
usage, so we should never be printing "void" when the language is Rust.

PR rust/20110 concerns the type of an integer constant that is too
large for "i32", the default integer type. This patch changes the
type of such a constant to i64. This is important because such values
are often addresses, so truncating them by default is unfriendly.
Built and regtested on x86-64 Fedora 23.

This updates the gdb test suite for Rust.
