Implement gpr1 and fpu save/restore functions per the ABI v2 documentation.

There is no "ABI v2".  This is the ELFv2 ABI, it is a name, it is not a
version 2 of anything (in fact, it is version 1 everywhere).

The same functions are needed and used in other ABIs, too.

But, why do this patch?  You just need

+LIBGCC         := $(shell $(CC) $(KBUILD_CFLAGS) -print-libgcc-file-name)

+libs-y += $(LIBGCC)

and nothing more.  It is required for proper functioning of GCC to link
with the libgcc support library.
