A couple comments:

1. Please use -mevexrcig.
2. Please remove force_rounding_bits and just do

else if (evexrcig)
  i.vex.bytes[3] |= 0x10 | (evexrcig << 5);

and make sure there is one space between "0x10 |" and  "(evexrcig << 5);".
3. Sync against trunk since I renamed OPTION_omit_lock_prefix
to OPTION_OMIT_LOCK_PREFIX.
