Tim Northover 1e8839302b AArch64: remove ConstantIsland pass & put literals in separate section.
This implements the review suggestion to simplify the AArch64 backend. If we
later discover that we *really* need the extra complexity of the
ConstantIslands pass for performance reasons it can be resurrected.
