We dont use C++14 features yet, why do we have to push /std:c++14?

I've removed this, and also got rid of the mentions of libedit (the cmake flag to disable it no longer exists)

@swift-ci please smoke test |

@hughbe are you okay with this going in before the rest of the patches? (I dont have a strong preference). |
|
Fine by me - order doesn't matter for any of the patches. couple of changes might need to be made though, e.g remove libedit, get rid of c++ 14 flag. |

| - Windows doesn't currently have a build script. You'll need to run commands manually to build Swift on Windows. | ||
| - Release/RelWithDebInfo modes have not been tested and may not be supported. | ||
| - x86 has not been tested. |

FYI, the cross-compilation based windows support has been tested and shown to be working :-).

Awesome! I meant a from-windows build (not X compilation)
I know I'm having some problems with release mode not working, though - I hit an assertition compiling the stdlib

Is there a particular reason to use a debug build of ICU instead of a release ICU build as it is an external dependency?

Nope, just the one I've tested.
