Add port done awhile ago for the ARC cpu.
* arc/arc.h: New file.
* arc/arc.c: New file.
* arc/arc.md: New file.
* arc/initfini.c: New file.
* arc/lib1funcs.asm: New file.
* arc/t-arc: New file.
* arc/xm-arc.h: New file.
* ginclude/va-arc.h: New file.
* ginclude/stdarg.h: Include va-arc.h ifdef __arc__.
* ginclude/varargs.h: Likewise.
* Makefile.in (USER_H): Add va-arc.h.
* configure.in (arc-*-elf*): Recognize.
* longlong.h: Add ARC support.
Mostly so I can test changes in snapshot scripts.
* expr.c (clear_storage): Use CONST0_RTX instead of const0_rtx.
when clearing non-BLKmode data.
Fixes sparc problem.
