// Given a requested allocation amount (in elements) and (potentially) the
// length of an array for which elements are being allocated, compute an actual
// allocation amount (in elements). (Allocation amounts include space for an
// ObjectElements instance, so a return value of |N| implies
// |N - ObjectElements::VALUES_PER_HEADER| usable elements.)

// Beyond that, we use this formula:
//
// count(n+1) = Math.ceil(count(n) * 1.125)
//
// where |count(n)| is the size of the nth bucket measured in MiSlots.
//
// These counts lets us add N elements to an array in amortized O(N) time.
// Having the second class means that for bigger arrays the constant factor is
// higher, but we waste less space.
//
// There is one exception to the above rule: for the power-of-two cases, if the
// chosen capacity would be 2/3 or more of the array's length, the chosen
// capacity is adjusted (up or down) to be equal to the array's length
// (assuming length is at least as large as the required capacity). This avoids
// the allocation of excess elements which are unlikely to be needed, either in
// this resizing or a subsequent one. The 2/3 factor is chosen so that
// exceptional resizings will at most triple the capacity, as opposed to the
// usual doubling.
// * preserve amortized O(N) time to add N elements;
// * minimize the number of unused elements beyond an array's length, and
// * provide at least SLOT_CAPACITY_MIN elements no matter what (so adding
// the first several elements to small arrays only needs one allocation).
