Instructions in VEX exception class 6 generally look at the value of
VEX.W. Note that the manual places some instructions incorrectly in
class 4, for example VPERMQ which has no non-VEX encoding and no legacy
SSE analogue. AMD does a mess of its own, as documented in the comment
that this patch adds.
Most of them are checked for VEX.W=0, and are listed in the manual
(though with an omission) in table 2-16; VPERMQ and VPERMPD check for
VEX.W=1, which is only listed in the instruction description. Others,
such as VPSRLV, VPSLLV and the FMA3 instructions, use VEX.W to switch
between a 32-bit and 64-bit operation.
Fix more of the class 4/class 6 mismatches, and implement the check for
VEX.W in TCG.

* There are a couple cases in which instructions (e.g. MOVD) write the
* whole XMM or MM register but are established incorrectly in the manual
* as "d" or "q". These have to be fixed for the decoder to work correctly.
+ *
+ * Speaking about imprecisions in the manual, the decoder treats all
+ * exception-class 4 instructions as having an optional VEX prefix, and
+ * all exception-class 6 instructions as having a mandatory VEX prefix.
+ * This is true except for a dozen instructions; these are in exception
+ * class 4 but do not ignore the VEX.W bit (which does not even exist
+ * without a VEX prefix). These instructions are mostly listed in Intel's
+ * table 2-16, but with a few exceptions.
+ *
+ * The AMD manual has more precise subclasses for exceptions, and unlike Intel
+ * they list the VEX.W requirements in the exception classes as well (except
+ * when they don't). AMD describes class 6 as "AVX Mixed Memory Argument"
+ * without defining what a mixed memory argument is, but still use 4 as the
+ * primary exception class... except when they don't.
+ *
+ * The summary is:
