* Makefile.in (LIBGCC_DEPS): Add libgcc2.h.
* libgcc2.c (__clz_tab[], __popcount_tab[]): Set the fixed dimension of
these arrays.
* libgcc2.h (__clz_tab[], __popcount_tab[]): Add exports of 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.
