Currently the definition of TypedArray is guarded by ENABLE(3D_CANVAS) ||
ENABLE(BLOB). It has been used in the following features:
- File API: FileReader and BlobBuilder
- XMLHttpRequest: send and response
We do not add an additional check expression when TypedArray is added to
XHR. We should do that but it will incur updating lots of files. If
TypedArray is used in another conditional feature, we will have to repeat
the same update.
I think it would be better if we could use a single guard or remove the
