Fixed iOS build after *T removal
librustc: Remove the `&LIFETIME EXPR` production from the language.

This was parsed by the parser but completely ignored; not even stored in
the AST!

This breaks code that looks like:

    static X: &'static [u8] = &'static [1, 2, 3];

Change this code to the shorter:

    static X: &'static [u8] = &[1, 2, 3];

Closes #15312.

trans::foreign: Simplify some code by using our builder impl
windows: Unicode console support.
Adds a WindowsTTY for libnative that converts between UTF-8 and UTF-16.

This implementation does have the minor issue of not handling things correctly when a codepoint is split across multiple writes or reads, but its better than not having unicode support at all.

Adds a Windows specific struct `WindowsTTY` in `libnative` and make `tty_open` create that struct on Windows. Adds needed functions and constants to `c_win32.rs`.

Libuv still needs to be updated before #15028 can be closed.
