specialize arm64 allTrue()/anyTrue()

aarch64 added vector-wise add/mul/min/max instructions.
We can use min and max to implement allTrue() and anyTrue(),
respectively.

(This CL is mostly so I don't forget these intrinsics exist.)

In assembly, these actually compile to two instructions,
the folding operation into a vector register, then a move
from the vector register to a general purpose register.
