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. This fixes PR3876. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67682 91177308-0d34-0410-b5e6-96231b3b80d8
