      Change to the handling of floating point zeros within numeric type · 3fe8030e

      specifiers by Raymond Toy. With these changes -0.0 and 0.0 and
      considered separate on the float type intervals which is more natural
      for many arithmetic function derive type optimizers.  These changes
      are dependent upon the :negative-zero-is-not-zero feature.

      Improved support for (complex single-float) and (complex double-float) · 4c3b1bb6
      dtc authored
      types. Adds storage classes to the backend for these so they can be
      stored in registers or on the stack without consing; new primitive
      types etc. Also adds (simple-array (complex {single,double}-float))
      array types to avoid consing and speed vectors operations.  All
      these changes are conditional on the :complex-float feature. More work
      is needed to exploit these changes: improving the type dispatch in the
      various function; maybe compiler transforms or more VOPs to handle
      common functions inline.

      Support for some specialised signed array types: (signed-byte 8), · d5d4504f
      dtc authored
      (signed-byte 16), (signed-byte 30), (signed-byte 32).  These patches
      include the general support and the x86 backend support; more to
      follow. The important changes are conditional on the :signed-array
      feature so shouldn't affect the source without this feature. This work
      has been driven by Raymond Toy.
