This revision was committed January 7, 2014. The next revision deleted runtime/mfinal.c. That will be done in a subsequent merge. This merge changes type descriptors to add a zero field, pointing to a zero value for that type. This is implemented as a common variable. * go-gcc.cc (Gcc_backend::implicit_variable): Add is_common and alignment parameters. Permit init parameter to be NULL. From-SVN: r211249
