followed by low; anything else is invalid.

No more random NUL ASCII characters on output now.

have special treatment in the compiler anymore.

o Convert x/n to x*(1/n) when n is a power of two since 1/n has an
  exact representation.
o Convert 2*x to x+x.

 * src/lisp/os.h
   * Move macros and definitions for FPU save/restore from here.
 * src/lisp/arch.h
   * Put architecture neutral stuff from os.h here.
 * src/lisp/ppc-arch.h
 * src/lisp/sparc-arch.h
 * src/lisp/x86-arch.h
   * Implement the FPU save/restore macros here for each supported
     architecture.

 src/lisp/gencgc.c:
 * Move the macros for fpu buffers from gencgc.c to here.
 src/lisp/x86-arch.c:
 * Use the new save_fpu_state instead of fpu_save.  And apply to all
   OSes.

 * Min OSX version is 10.5 now.  Don't have access to anything older
   than 10.5 anyway.

src/lisp/gencgc.c:
o Save and restore the FPU state in alloc().

src/compiler/x86/sap.lisp:
o Don't need to use :save-p anymore because the allocation routine
  saves an live registers anyway.  This improves code generation as
  well.

src/general-info/release-20d.txt:
o Update.

stack space to hold the SSE2 state.  (Forgot to add extra bytes for
16-byte alignment!)

src/lisp/x86-assem.S:
o Remove the (now) unused alloc_to_<reg> functions.

src/compiler/x86/macros.lisp:
o Simplify the not-inline-allocation to use the same routines as
  inline allocation.

src/bootfiles/20c/boot-2012-07-1-x86-cross.lisp:
o X86 cross-compile script

src/compiler/x86/macros.lisp:
o New inline-allocation to call our new overflow routine.

src/lisp/x86-assem.S:
o New alloc_overflow routine.

src/tools/cross-scripts/cross-x86-x86.lisp:
o Export all symbols in VM that are external symbols in OLD-VM with
  the corresponding symbol name.

point operations should occur in allocation or GC now, except when
printing stats.
