I was able to build recent Linux v4.14.y kernels with several "clang-7
trunk" which needs some additional patches.

Matthias offers a patchset [1] with Linux v4.14 vanilla as base.

Some of the patches are in linux-stable-4.14.y and obsolete now.
If you use a higher clang version like 5 or 6, the patches labeled
with "CLANG-3" and CLANG-4" are not needed.
AFAICS the patches labeled with "UPSTREAM" are of interest.

My 4.14.54-1-iniza-llvmlinux kernel boots on bare metal as an example
(dmesg attached).
