Clang's assembler does not like the syntax of the cmpdi:

                              ^

         cmpdi   12,RELACOUNT@l
                   ^
Enclosing RELACOUNT in () makes it is happy. Tested with GCC 8 and Clang
8 (trunk).

Is clang going to fix this?  You also might want to add a comment that
this is a workaround for that broken assembler.
