[PATCH 1/2, libgcc]: Implement _divmoddi4

Authentication-results: sourceware.org; auth=none

This function will be used in a follow-up patch to implement
TARGET_EXPAND_DIVMOD_LIBFUNC for x86 targets. Other targets can call
this function, so IMO it should be part of a generic library.

2016-10-31  Uros Bizjak  <ubizjak@gmail.com>

    * Makefile.in (LIB2_DIVMOD_FUNCS): Add _divmoddi4.
    * libgcc2.c (__divmoddi4): New function.
    * libgcc2.h (__divmoddi4): Declare.
    * libgcc-std.ver.in (GCC_7.0.0): New. Add __PFX_divmoddi4
    and __PFX_divmodti4.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32} with a
follow-up target-dependent  patch.

OK for mainline?

Uros.
