  these arrays.

* longlong.h: Only provide a prototype for the __clz_tab[] array if this
  header has not been included from libgcc2.h.
* config/stormy16/stormy16-lib2.c: Include libgcc2.h rather than defining
  own types.
  Provide prototypes for exported functions.
  Use the __clz_tab[] and __popcount_tab[] arrays provided by libgcc2.c.
