  /* The naming convention is:

     - to use the name of the function if the rules are very specific to
       a particular function (e.g. svext, for which the range of the
       final immediate value is in no way generic).

     - to use names like "unary" etc. if the rules are somewhat generic,
       especially if there are no ranges involved.

     When using generic names, the handling of the final vector argument
     can be modified as follows:

     - an "_n" suffix changes the argument from a vector to a scalar.

     - an "_opt_n" suffix says that there are two forms of each function:
       one in which the argument is the usual vector, and one in which it
       is replaced by a scalar.

     - "_int" and "_uint" replace the argument's element type with a
       signed or unsigned integer of the same width.  The suffixes above
       then indicate whether this final argument is or might be a scalar.

     - "_int64" and "_uint64" similarly replace the argument's element type
       with int64_t or uint64_t.

     - "_wide" replaces the argument's element type with a 64-bit integer
       of the same signedness.  This only makes sense for integer elements.

     - "_lane" indicates that the argument is indexed by a constant lane
       number, provided as an immediately-following argument of type uint64_t.

     Also:

     - "inherent" means that the function takes no arguments.

     - "_rotate" means that the final argument is a rotation amount
       (0, 90, 180 or 270).

     - "_scalar" indicates that all data arguments are scalars rather
       than vectors.

     - in gather/scatter addresses, "sv" stands for "scalar base,
       vector displacement" while "vs" stands for "vector base,
       scalar displacement".

     - "_pred" indicates that the function takes an svbool_t argument
       that does not act as a governing predicate..  */
