ix86: don't recognize/derive Q suffix in the common case
Have its use, except where actually legitimate, result in the same "only
supported in 64-bit mode" diagnostic as emitted for other 64-bit only
insns. Also suppress deriving of the suffix in Intel mode except in the
legitimate cases. This in exchange allows dropping the respective code
from match_template().
To maintain reasonable diagnostics (in particular to avoid "`mov' is
only supported in 64-bit mode" on the SIMD forms of MOVQ) we need to
defer parse_insn()'s emitting of errors unrelated to prefix parsing.
Utilize i.error just like match_template() does.
Oddly enough despite gcc's preference towards FILDQ and FIST{,T}Q we
had no testcase whatsoever for these. Therefore such tests are being
added. Note that the removed line in the x86-64-lfence-load testcase
was redundant with the exact same one a few lines up.
