This patch adds the assembly/disassembly for the following instruction:

  SEL: Multi-vector conditionally select elements from two vectors.

for 2 and 4 registers

  The reference can be found here:

This patch also adds a new register class Predicate-as-counter (PN)

  PNRP8_15RegOp

The predicate register AArch64:P<x> is used as a predicate-as-count
register Pn<x>[idx].

To represent that (P<x> predicate as Pn<x>[idx] predicate as a counter) this
patch creates a new AsmOperand class PNRAsmOperand.

PRNAsmOperand inherits from PPRAsmOperand but with a new predicate method. The new
predicate method checks if the register operand is the new Register Kind
SMEPredicateAsCounter.
