Fix a bug in our autoupgrade support: in an argument list to a function call, we should treat "i64 zext" as the start of a constant expr, but "i64 0 zext" as an argument with an obsolete attribute on it (this form is already tested by test/Assembler/2007-07-30-AutoUpgradeZextSext.ll). Make the autoupgrade logic more discerning to avoid treating "i64 zext" as an old-style attribute, causing us to reject a valid constant expr.
