description: >
Return abrupt from ToInteger(start).
info: |
22.2.3.5 %TypedArray%.prototype.copyWithin (target, start [ , end ] )
%TypedArray%.prototype.copyWithin is a distinct function that implements the
same algorithm as Array.prototype.copyWithin as defined in 22.1.3.3 except
that the this object's [[ArrayLength]] internal slot is accessed in place of
performing a [[Get]] of "length" and the actual copying of values in step 12
must be performed in a manner that preserves the bit-level encoding of the
source data.
