I don't understand this part.

It's not related to the bug, just something I discovered while debugging.
Basically, inlining will generate an instruction that may at the end not have
the type the inferrer found, for example:
JS('UInt32Array', 'new UInt32Array()')

The inferrer actually knows more about the type, so we just use what the
inferrer found.
