Replace String.charAt() with HIR.
Replace String.charAt() with HArrayLength, HBoundsCheck and
HArrayGet. This allows GVN on the HArrayLength and BCE on
the HBoundsCheck as well as using the infrastructure for
HArrayGet, i.e. better handling of constant indexes than
the old intrinsic and using the HArm64IntermediateAddress.
