      Add a check that objects obtained from the stack in · 54c1961a
      dtc authored
      sub-access-debug-var-slot (x86) are valid.  Debug variable locations
      are not always valid, and on the x86 there can be non-descriptor
      objects on the stack.
      
      Cleanup the sap-ref code in sub-access-debug-var-slot and
      sub-set-debug-var-slot which had been using convoluted code to work
      around sap-ref bugs that have since been fixed.

      Merge in changes to the x86 backend from the gencgc branch, allowing · 725ab9ee

      common binaries to be run on both:
      
      * The immediate-stack storage class has been removed, this is
      unnecessary as the descriptor-stack SC can be used. It may have once
      been part of some GC stragety to reduce the number of stack slots that
      needed to be noted for a GC.
      
      * The object allocation has been abstracted and cleaned up. This
      should produce slightly faster smaller code with CGC, and can be
      compiled to support inline allocation with GENCGC.  CGC compiled code
      will run under GENCGC, and GENCGC binaries that don't use inline
      allocation will run under CGC.
      
      * A random hash is now placed in the unused symbol object slot (the
      symbol-hash slot). This saves flushing the info cache at each GC, and
      may have other uses for symbol based hash tables. Should help MP
      safety.
      
      * Common set of static symbols used by both CGC and GENCGC.
      
      * Corrections to the stack-ref VOP; now returns lisp objects not
      unsigned numbers. Required some patches to debug-int.
      
      * Inline unsigned/signed byte 32 to bignum allocation enabled.
      
      * Support for the x86 xadd instruction applied to instance slot and
      symbol values - may be handy for some MP code.
      
      * Bump up the FASL file version from 1 to 2.

      Improved support for (complex single-float) and (complex double-float) · 4c3b1bb6

      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.

      Ok, here are the updated patches to make the same cmucl lisp.core work
      across OS versions under irix, still by making tzname resolved at runtime
      (on irix only).
