Enable -Wimplicit-fallthrough for Clang for 5.14-rc7

Hi Linus,

Please, pull the following patch that 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. :)

Thanks!
