Usage with "Clang for Windows"

NOTE: For the purposes of this discussion I'm not talking about using Clang toolset in MSVC.

Is Clang properly supported with Premake on Windows without using clang-cl?

In the 5.0.0 and the latest release and probably earlier versions the regular clang executable (taking GCC flags) works in Windows and produces valid MSVC compatible binaries.

According to this blog post in order for clang to produce MSVC compatible binaries a specific triple must be sent as the target platform:

Alternatively, if you have a cross-platform project and want to use gcc-style flags for your Windows build, you can pass a Windows triple (e.g. --target=x86_64-windows-msvc) to regular Clang, and it will produce MSVC-ABI-compatible output.

Because of the wording of the blog around that paragraph it is confusing if the target triple is required when building on Windows or if it is only required when on a different platform and performing a cross compilation.

Start by reproducing the regular clang executable workflow on Windows described in the issue, with and without the x86_64-windows-msvc target triple. Compare the generated behavior with the expected MSVC-compatible output; done means the support question is resolved and any required Premake change is covered by a regression test or documented behavior.
