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.
(match_template): Remove fldcw special case. Adjust q-suffix handling
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.

'high' and 'low' parts of an operand, which the parser previously
accepted while neither telling that it's not supported nor that it
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.

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.
(OP_E): Handle new *_mode values. Correct pointer specifications for
memory operands. Consolidate output of index register.
(OP_G): Handle new *_mode values.
(OP_I): Handle const_1_mode.
(OP_ESreg, OP_DSreg): Generate pointer specifications. Indicate
respective opcode prefix bits have been consumed.
(OP_EM, OP_EX): Provide some default handling for generating pointer
specifications.
