JavaScript Backend: Fix offset out of bounds panic

Description

This is a real bug in the current backend that occurs by passing an illegal offset to a JS DataView object. We use these objects for Addr# and ByteArrays. It may be possible that this is coming from an incorrectly implemented primop.

Here's an example of the failure:

Wrong exit code for T20509()(expected 0 , actual 2 )
Stdout ( T20509 ):
uncaught exception in Haskell main thread: RangeError: Offset is outside the bounds of the DataView
RangeError: Offset is outside the bounds of the DataView
