  Makefile: Enable -Wimplicit-fallthrough for Clang (2021-09-13 23:47:12 -0500)

Enable -Wimplicit-fallthrough for Clang for 5.15-rc2

Hi Linus,

Please, pull the following patches that fix the last warnings in
x86_64, ARM and MIPS reported by kernel test robot, and enables
-Wimplicit-fallthrough for Clang 14+, globally.

We had almost 40,000[1] of these issues for Clang in the beginning,
and there might be a couple more out there when building some
architectures with certain configurations. However, with the
recent fixes, I think we are in good shape and it is now possible
to enable -Wimplicit-fallthrough for Clang, with this finally getting rid of
the unintentional fallthrough bug-class in the kernel, entirely. :)
