Calling window.js object methods with an incompatible receiver causes a hard crash

[Hamish Milne]

Repro console commands:

• ImageBitmap.prototype.width
• ImageBitmap.prototype.encode()
• ImageData.prototype.width
• CanvasRenderingContext2D.prototype.getTransform()

etc.

Expected output: Something like

TypeError: Method get ArrayBuffer.prototype.byteLength called on incompatible receiver #<ArrayBuffer>
    at ArrayBuffer.get byteLength [as byteLength] (<anonymous>)

Actual output: crash.

(This is presumably because the API wrapper functions don't yet check the result of info.This())

Thanks for the report. This crashes consistently.
