This patch adds support for the following instructions:
CNTB CNTH - Determine the number of active elements implied by
CNTW CNTD the named predicate constant, multiplied by an
immediate, e.g.
cnth x0, vl8, #16
CNTP - Count active predicate elements, e.g.
cntp x0, p0, p1.b
counts the number of active elements in p1, predicated
by p0, and stores the result in x0.
