i386: Mark XMM4-XMM6 as clobbered by encodekey128/encodekey256

encodekey128 and encodekey256 operations clear XMM4-XMM6.  But it is
documented that XMM4-XMM6 are reserved for future usages and software
should not rely upon them being zeroed.  Change encodekey128 and
encodekey256 to clobber XMM4-XMM6.
