Message:

FTL should support typed array GetByVal and related ops
​https://bugs.webkit.org/show_bug.cgi?id=120965

Reviewed by Oliver Hunt.

This adds support for typed array instantiations of the following DFG IR ops:

• GetByVal

• GetIndexedPropertyStorage

• CheckArray

• GetArrayLength

This also adds CheckArray for Int32/Double/Contiguous arrays.
