On a target with a 16-bit mask (for example), we would choose the type of an integer literal "1024" to be an int16. Previously, we used an int32, which is a worse fit and leads to less efficient code than an int16 on a 16-bit mask target. (However, we'd still give an integer literal 1000000 the type int32, even in a 16-bit target.) Updated the tests to still pass with 8 and 16-bit targets, given this change.
