insns.dat: Fix issue #171 - valid prefixes not allowed

Browse source 
Instructions like IRET, POPF and PUSHF used to not have a operand size
specifier but after applying macros they received the 'osm' one -
meaning must be the same as the BITS mode. Which is not true for these
instructions, using the operand size prefix doesn't change their
encoding and their default 64-bit encoding is the 32-bit version.

Align these with other similar instructions like RET, RETF and use the
'od#' keyword which returns their previous behavior.
