8d00819790 ghc-7.6: add missing Num instance for Bits 
Fixes the following build failure:
    src/runtime/haskell/Data/Binary/IEEE754.lhs:256:17:
        Could not deduce (Num a) arising from a use of `mask'
        from the context (Bits a)
          bound by the type signature for
                     clamp :: Bits a => BitCount -> a -> a

0f7ebcc10d Fix for a PGF portability problem 
GF produced slightly different PGF files on 64-bit systems and 32-bit systems.
This could cause problems when a PGF was produced on a 32-bit system and used
on a 64-bit system.

To fix this, the GF compiler and the Haskell PGF run-time library now reads
and writes PGF files like the 32-bit version even when compiled on a 64-bit
system.

Note: the Haskell type Int is still used internally in GF, which could be
32 bits or 64 bits...

78a2a90903 PGFService.hs: fix type error caused by change to PGF.graphvizParseTree 
Note that some of the graphviz functions have backwards incompatible changes
that might also affect other clients of the PGF run-time library.

Also added graphvizDefaults and export it together with GraphvizOptions from 
the PGF run-time library.
