Partial fix for this PR. Default function parameters to signed integer, just like everything else in CBE. The bug was caused by incorrectly introducing parameter attributes feature by choosing "signed" parameter if the SExtAttribute was specified. Howeer, if no attribute is specified, this causes it to become unsigned which is incorrect. Reversing the logic so that signedness is detected by "not ZExtAttribute" set fixes the issue. This fixes 197.parser but there is more to do. Any comparison and possibly other operators involving arguments may need to correctly cast the parameter before its use, depending on the sign of the operator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33034 91177308-0d34-0410-b5e6-96231b3b80d8
