[SystemZ] Fix fallout from r233543 on no-assert builds
Browse files Browse the repository at this point in the history 
Test cases must not check for symbolic variable names that are not
present in IR generated by no-assert builds.

Fixed by testing a more complete subset of the va_arg dataflow,
without relying on variable names.
