operating on integers as well as control instructions to short ones
as expected by AT&T syntax. Translate 'd' suffix to short one only for
floating point instructions operating on non-integer operands.

to permit it on fild/fistp/fisttp in AT&T mode.
(process_suffix): Don't guess DefaultSize insns' suffix from
stackop_size for certain floating point control instructions. Guess
suffix for branch and [ls][gi]dt based on flag_code. Split error
messages for Intel and AT&T syntax, and make the condition more strict
for the former. Adjust suppressing of generation of operand size
overrides.

ignored the remainder of the line following these supposed keywords.

distinction. Adjust a few others for Intel mode. Remove *FP uses from
all non-floating-point instructions. Unite 32- and 64-bit forms of
movsx, movzx, and movd. Adjust floating point operations for the above
changes to the *FP macros. Add DefaultSize to floating point control
insns operating on larger memory ranges. Remove left over comments

operands.
(dis386): Make far jumps and calls have an 'l' prefix only in AT&T
mode. movmskpX's, pextrw's, and pmovmskb's first operands are Gdq.
pinsrw's second operand is Edqw.
(grps): 1-bit shifts' and rotates' second operands are I1. cmpxchg8b's
operand is Eq. movntq's and movntdq's first operands are EM. s[gi]dt,
fldenv, frstor, fsave, fstenv all should also have suffixes in Intel
mode when an operand size override is present or always suffixing.
More instructions will need to be added to this group.
(putop): Handle new macro chars 'C' (short/long suffix selector),
'I' (Intel mode override for following macro char), and 'J' (for
adding the 'l' prefix to far branches in AT&T mode). When an
alternative was specified in the template, honor macro character when
specified for Intel mode.

memory operands. Consolidate output of index register.
