[patch] put DPD decimal float support in shared libgcc

[Janis Johnson]

By design, the arithmetic/comparison/conversion functions for decimal
floating point support were originally added only to the static
libgcc because we thought the APIs might change later.  We'd now like
to include this support in the shared version of libgcc as well.

I've done this only for the DPD support because I'm not clear on how
much of the BID support would need to be made visible outside of 
libgcc.

Bootstrapped and regression-tested on powerpc64-linux with -m32/-m64.
Bootstapped with only C and minimally tested on x86_64-linux for both
BID and DPD decimal float support.  OK for trunk?
