Drop the requirement that getInitialValueOfAllocation() must be passed an allocator function, shifting the responsibility for checking that into the function (which it does anyway). The motivation is to avoid some calls to isAllocationFn(), which has somewhat ill-defined semantics (given the number of allocator-related attributes we have floating around...)

(For this function, all we eventually need is an allockind of zeroed or uninitialized.)
