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
