Data-dependent SVP64 Vectorised Operations involving the creation or
modification of a CR require an extra two bits, which are not available
in the compact space of the `MODE` Field. With the concept of element
-width overrides being meaningless for CR Fields it is possible
-to use the `ELWIDTH` field for extra fields.

-Condition Register based operations such as `mfcr` and `crand`
-can thus be made more flexible. However the rules that apply in
-this section also apply to future CR-based instructions. Note
-that these rules and the alternative mapping **only** applies

-the sole exclusive result. This section **does not** apply

SVP64 RM `MODE` (includes `ELWIDTH` bits) for CR-based operations:
|dz |VLi| 01 | inv | CR-bit | normal mode |
|sz |VLi| 01 | inv | dz Rc1 | VLSET mode |
-Operations that actually produce or alter CR Field as a result
-do not also in turn have an Rc=1 mode. However it makes no
-sense to try to test the 4 bits of a CR Field for being equal
-or not equal to zero. Moreover, the result is already in the
-form that is desired: it is a CR field.

There are two primary different types of CR operations:
* Those which have a 5-bit operand (referring to a bit within the
whole 32-bit CR)
-Examining these two as has already been done it is observed that
-the difference may be considered to be that the 5-bit variant
-provides additional information about which CR Field bit
-(EQ, GE, LT, SO) is to be operated on by the instruction.

Thus, logically, we may set the following rule:
