      Use a separate stack for alien value allocation on the x86. It had · 1975d13a
      dtc authored
      been sharing the control stack with the compiler which could cause
      trouble (pushes and pops out of order, holes in arguments built up on
      the stack, exposed stack that can be written over on interrupt, etc)
      
      Assigned a static symbol, x86::*alien-stack*, and by default set it to
      the old C stack. A program many rebind this if it needs more room or
      wants the allocation elsewhere.
      
      The *alien-stack* is saved with the dynamic environment so is restored
      with a non-local exist. It's not save on function entry/exit so you
      need to take care to match an allocation with a deallocation.
      
      Makes use of new VOPs which are already in place.
      
      Backout an old alien stack deallocation hack.

      Fix multiplication bug. Multiply-bignum-and-fixnum was using the · f3718883
      dtc authored
      following to convert a fixnum to an (unsigned-byte 32) representation:
      (%fixnum-to-digit (if pos val (- val)))
      This broken when val was (- #x20000000) as #x20000000 is not a fixnum as
      expected by %fixnum-to-digit.
      Similar problem in multiply-fixnums.
      It may be best to just leave it up to the compiler to move the positive
      fixnum to an unsinged register here.
