Bug#797626: llvm-toolchain-3.6: apply InstCombine patch for rustc

[Ximin Luo]

Source: llvm-toolchain-3.6
Severity: important
Tags: upstream patch

Dear Maintainer,

Please apply the attached patch. The origin is:

http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20150622/282940.html

and it is necessary to make later versions of rustc compile correctly, see 

https://github.com/rust-lang/rust/issues/26468

I have tested the patch against 1:3.6.2-1 and it applies cleanly with an offset.

Thanks,

X
