Rollup merge of #95740 - Amanieu:kreg0, r=nagisa
asm: Add a kreg0 register class on x86 which includes k0

Previously we only exposed a kreg register class which excludes the k0
register since it can't be used in many instructions. However k0 is a
valid register and we need to have a way of marking it as clobbered for
clobber_abi.

Fixes #94977
