+description: >
+ Set values from different instances using the same buffer and same
+ constructor. srcBuffer values are cached.
+info: |
+ 22.2.3.23.2 %TypedArray%.prototype.set(typedArray [ , offset ] )
+
+ 1. Assert: typedArray has a [[TypedArrayName]] internal slot. If it does not,
+ the definition in 22.2.3.23.1 applies.
+ ...
+ 23. If SameValue(srcBuffer, targetBuffer) is true, then
+ a. Let srcBuffer be ? CloneArrayBuffer(srcBuffer, srcByteOffset, srcLength,
+ %ArrayBuffer%).
+ b. NOTE: %ArrayBuffer% is used to clone srcBuffer because is it known to not
+ have any observable side-effects.
+ ...
+ ...
+ 27. If SameValue(srcType, targetType) is true, then,
+ a. NOTE: If srcType and targetType are the same, the transfer must be
+ performed in a manner that preserves the bit-level encoding of the source
+ data.
+ b. Repeat, while targetByteIndex < limit
+ i. Let value be GetValueFromBuffer(srcBuffer, srcByteIndex, "Uint8").
+ ii. Perform SetValueInBuffer(targetBuffer, targetByteIndex, "Uint8",
+ value).
