I disabled putting the new global into the same COMDAT as the function for now. There's a fundamental problem when we inline references to the global but still have the global in a COMDAT linked to the inlined function. Since this is only an optimization there may be other versions of the COMDAT around that are missing the new global and hell breaks loose at link time. I hope the chromium build doesn't break this time :) llvm-svn: 231564
