Fields without first partially decoding the 32-bit suffix. Similar to
the "Forms" (X-Form, D-Form) the `RM` format is individually associated
with every instruction. However this still does not adversely affect Multi-Issue

+Decoding because the identification of the *length* of anything in the

Extreme caution and care must be taken when extending SVP64
in future, to not create unnecessary relationships between prefix and
