rust/src/libstd/macros.rs, branch 1.37.0

Rollup merge of #61720 - alexcrichton:libstd-cfg-if-dep, r=sfackler

std: Remove internal definitions of `cfg_if!` macro This is duplicated in a few locations throughout the sysroot to work around issues with not exporting a macro in libstd but still wanting it available to sysroot crates to define blocks. Nowadays though we can simply depend on the `cfg-if` crate on crates.io, allowing us to use it from there!

Fix missing semicolon in doc

2019-06-02T08:23:33+00:00

A semicolon is missing in the examples of compile_error. Macros that expand to items must be delimited with braces or followed by a semicolon.

Remove the unstable and deprecated mpsc_select

2019-05-17T19:16:52+00:00

This removes macro `select!` and `std::sync::mpsc::{Handle, Select}`, which were all unstable and have been deprecated since 1.32.

Remove the old await! macro

2019-05-09T17:49:39+00:00

This doesn't work anymore, and its continued presence is cause for confusion.
