Throws a TypeError if typedArray arg is not an Int32Array
info: |
Atomics.waitAsync( typedArray, index, value, timeout )
1. Return DoWait(async, typedArray, index, value, timeout).
DoWait ( mode, typedArray, index, value, timeout )
1. Let buffer be ? ValidateSharedIntegerTypedArray(typedArray, true).
ValidateSharedIntegerTypedArray ( typedArray [ , waitable ] )
5. If waitable is true, then
a. If typeName is not "Int32Array" or "BigInt64Array", throw a TypeError exception.
