Sure - for (most of?) the TSVC tests GCC is failing to vectorize there
should be a bugzilla open.  So if you have TSVC tests that LLVM can
vectorize but GCC can not then check if there is a bugzilla open.
If so, note that LLVM can vectorize, if not, open one.

I have now pushed the change.

Thanks,
Richard.
