merge from stable, revs:

  1.191.4.1 +2 -2      fptools/ghc/compiler/Makefile
  1.7.4.2   +38 -13    fptools/ghc/compiler/ghci/ByteCodeFFI.lhs
  1.58.4.2  +4 -3      fptools/ghc/compiler/ghci/ByteCodeGen.lhs
  1.25.4.1  +40 -10    fptools/ghc/compiler/ghci/ByteCodeLink.lhs

  Make the bytecode generation machinery print a helpful message if
  it has to give up due to lack of 64-bit support.

  Add various bits of supporting infrastructure for 64-bit values
  in the bytecode generator.  Making it all work is beyond the scope
  of a patchlevel release, so these are unused right now.

  1.25.4.2  +27 -7     fptools/ghc/compiler/ghci/ByteCodeLink.lhs

  Print a civilised and helpful error message if the bytecode linker
  should encounter a link failure.

  1.58.4.3  +6 -8      fptools/ghc/compiler/ghci/ByteCodeGen.lhs
  1.25.4.3  +1 -1      fptools/ghc/compiler/ghci/ByteCodeLink.lhs

  Also give civilised messages for interactive FFI link failures.

  1.25.4.4  +2 -1      fptools/ghc/compiler/ghci/ByteCodeLink.lhs

  Refine the runtime-link-failure msg a bit.
