x86-asm: Reorganize instr_type
Disjoint instruction types don't need to be a bit field, so
introduce an enumeration (3 bits). Also the 0x0f prefix can
be expressed by a bit, doesn't need a byte in the opcode field.
That enables to encode further prefixes still in 16 bit.
To not have to touch all insns do some macro fiddling filtering
out a 0x0f byte in the second position.
