Original change's description:
> [builtins]: Optimize CreateTypedArray to use element size log 2 for calculations.
>
> TypedArrayElementsInfo now represents an element's size as a log 2 and typed as
> uintptr.  This simplifies and speeds up (avoids possible HeapNumber allocations) a
> number of calculations:
>
>   - Number of Elements (length) -> Byte Length - is now a WordShl
>   - Byte Length -> Number of Elements (length) - is now a WordShr
>   - Testing alignment (byte offset or length)  - is now a WordAnd
>
> These element/byte length related calculations are encapsulated in
> TypedArrayElementsInfo as struct methods.
>
> This reduces the size of CreateTypedArray by 2.125 KB (24%) on Mac x64.release:
>   - Before: 9,088
>   - After:  6,896
>
> This improves the performance of the following microbencmarks
>   - TypedArrays-ConstructWithBuffer: ~87%
>   - TypedArrays-SubarrayNoSpecies:   ~28%
>
