           Summary: FIXME in B3Validate.cpp for ArgumentReg nodes
    Classification: Unclassified

           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

We could alias a int32 ArgumentReg with a int64 ArgumentReg if they are the same reg.  Then they would get incorrectly treated the same.  For int32 argument values, we need to use Trunc(ArgumentReg).
