* Remove the name dependence on EAX in move-to-word/integer.

* Change move-from-signed to do a fixnum check using one branch
  instead of two.

* Remove move-from-signed and move-from-unsigned assembly routines and
  the commented out code that refers to them.

This change allow cmucl to fold identity operations as in

(defun foo (x)
  (declare (float x))
  (* x 1))

Previously, cmucl wouldn't change (* x 1) to just x. because the
declaration of x is represented internally as a union type.

Forgot to do this when we added BYTE-BASH-COPY for REPLACE.

From ticket 81, the tests are now:

{{{

; Evaluation took:
;   0.49 seconds of real time
;   0.481813 seconds of user run time
;   0.003624 seconds of system run time
;   1,490,776,936 CPU cycles
;   [Run times include 0.13 seconds GC run time]

So the new string-reverse* is 20 times faster for strings without
surrogates and 10 times faster for strings containing only surrogates.

Wrap exports in eval-when for x86 as was done for sparc and add
CHAR-BYTES to x86-x86 cross-compile script.

CHAR-BYTES to x86-x86 cross-compile script.

Only the change for CHAR-BYTES is needed for cross-compiling from x86
to x86, but I think the other changes will be needed if you do a
cross-compile from some other arch to x86.

CHAR-BYTES to ppc cross-compile script.

This is untested.

  When export lost its compile-time effects and became a normal
  function, the exports in many files no longer took affect while
  compiling the file.  This change makes the compile-time effects
  happen as before in selected files. With this change, the sparc port
  can be cross-compiled from x86 again.

 * Config.sparc_common
   * OS_LINK_FLAGS is not common, so remove it.
 * Config.sparc_gcc
 * Config.sparc_sunc
   * Set OS_LINK_FLAGS appropriately.

 * GNUmakefile

 * Config.x86_common

Just use plain describe, which is close enough.

cc is Sun's C compiler, not an alias to gcc.
