Alex Crichton 7e6c9f3635 Switch to rust-lang-nursery/compiler-builtins ... This commit migrates the in-tree `libcompiler_builtins` to the upstream version at https://github.com/rust-lang-nursery/compiler-builtins. The upstream version has a number of intrinsics written in Rust and serves as an in-progress rewrite of compiler-rt into Rust. Additionally it also contains all the existing intrinsics defined in `libcompiler_builtins` for 128-bit integers. It's been the intention since the beginning to make this transition but previously it just lacked the manpower to get done. As this PR likely shows it wasn't a trivial integration! Some highlight changes are: * The PR rust-lang-nursery/compiler-builtins#166 contains a number of fixes across platforms and also some refactorings to make the intrinsics easier to read. The additional testing added there also fixed a number of integration issues when pulling the repository into this tree. * LTO with the compiler-builtins crate was fixed to link in the entire crate after the LTO process as these intrinsics are excluded from LTO. * Treatment of hidden symbols was updated as previously the `#![compiler_builtins]` crate would mark all symbol *imports* as hidden whereas it was only intended to mark *exports* as hidden.		2017-07-05 07:08:36 -07:00
