Add inclusive range support for Rust
This is version 2 of the patch to add inclusive range support for
Rust. I believe it addresses all review comments.
Rust recently stabilized the inclusive range feature:
https://github.com/rust-lang/rust/issues/28237
An inclusive range is an expression like "..= EXPR" or "EXPR ..=
EXPR". It is like an ordinary range, except the upper bound is
inclusive, not exclusive.
This patch adds support for this feature to gdb.
Regression tested on x86-64 Fedora 27.
