I suggest u grep how this file is used.
Since it is included in xxInstrInfo.td and this is its only use, we can
conclude that this file does nothng more than defining some helper tablegen
classes and we thus can totally move these definitions into xxInstrInfo.td
and then remove XXInstFormat.td

Regards.
