            Fix a functional-dependency-related bug in
      	MERGE TO STABLE if it goes over conveniently
      		(but I rather think it may not)
      tcSimplifyRestricted works by (a) simplifying brutall to find out
      what the constrained type variables are, and (b) simplifying more
      gently, knowing the constrained type varaibles.  The bug is that
      in step (b) we were not doing the check-for-improvement-and-loop
      part, thinking that step (a) had alrady done all the improvement.
      But not so, as an example in the code now shows.
      Simple to fix.  I rather think we could tidy up these various loops.

      Have Literal.Literal support the representation of NULL pointers only,
      and not arbitrary pointer values.
      (MachAddr <some-pointer-value-as-an-Integer>) wasn't being used,
      except to handle nullAddr#. It (MachAddr) is a potential source of
      problems should the compiler start doing constant folding or other
      interesting operations over MachAddrs (think: interface files +
      cross-compilation), so we might as well scale back the representation
      of raw pointer values.

      Tidy up code that supports user/Haskell signal handlers.
      Signals.h now defines RTS_USER_SIGNALS when this is supported,
      which is then used elsewhere.

      Don't constant-fold (negateFloat# 0.0#), because the compiler's
      internal representation of floating-point literals (Rational) can't
      represent -0.0.  This means that
         main = print (-0.0)
      now gives the same results with -O as it does without.
      Fixes test arith005.

      NCG support for f.e.d. stdcall -- Literal.MachLabels now optionally carry
      the size (in bytes) of the stack frame it expects, if known. That just
      so happens to match what stdcall labels need to be annotated with when
      emitting them in the NCG..

      Two performance tweaks:
        - Use specialised indirections, which perform the right kind of
          return without needing to enter the object they point to.  This
          saves a small percentages of memory reads.
        - Tweak the update code to generate better code with gcc.  This
          saves a few instructions per update.
