Fixed a couple of bad bugs in the implementation of 'foreign export ccall dynamic'.

Move 4.01 onto the main trunk.

Relax restriction that 'foreign import' has got to be an IO action

avoid uncessary gcc warning

First take at 'foreign label's

- added primops for read&writing StablePtrs to ByteArrays, Adds and FOs
- egcs crashes in odd ways when encountering the typedefs we need to
  produce when compiling 'foreign import dynamic's. To workaround the
  problem, kludgily add a CCallTypedef constructor to AbsCSyn.AbstractC
  which the flattener will produce (at the toplevel) when encountering
  CCallOps inside COptStmts.
- augmented PrimOp.CCallOp to carry a unique when it represents a
  'foreign import dynamic' call. The CoreToStg pass ensures that these
  uniques are exactly that. They're used to eventuall generate (unique)
  typedef names.
