  [ARM] Correct the type on a predicate cast

A PREDICATE_CAST(PREDICATE_CAST(X)) can be converted to a
PREDICATE_CAST(X) as the operation can convert between any forms of
predicates (v4i1/v8i1/v16i1/i32). Unfortunately I got the type wrong on
one of the rarer converts, which would lead to invalid nodes during
isel. This fixes it up to use the correct type.
