  by Kazuho Oku <[email protected]>.
  This pull request has the following commits.
* gc.c: reduce # of args to 6 (max. of register args on x86-64) so
  that the `newobj_of_slowpass` can be called via TCO.
* gc.c (newobj_of), string.c (str_duplicate): for performance,
  the hot functions must be inlined.
* gc.c: for performance, preceding arguments of `.*newobj_of.*`
  must be same, so that the arg registers can be reused in case of
  TCO.
