Details

Right now, alu()'s demotion only works with promoted signed integers.  We should consider making it work with unsigned ones too, so that operations on a Uin32Array won't end up being done on doubles, with the ensuing double-to-int conversions on write.

See bug 628209 for rationale and testcases; one is also linked in the url field.
