[RFC] Testing builds with Clang

[Nick Desaulniers]

Hello,
Recently, a fair amount of effort has gone into compiling the kernel
with Clang/LLVM.  We were curious what might be some of the
requirements to getting 0-day coverage for Clang built kernels?

As in, does Clang need to support allmodconfig, randconfig, all
ARCH's, etc before 0-day can be turned on?  Such requirements can help
us set goals.

Also, is https://github.com/intel/lkp-tests the codebase for the 0-day bot?

Thanks,
~Nick Desaulniers
