were returned when calling out to a C function returning a float.

float-sse2.lisp:
o Remove the FLOAT-MOVE vop and add a FLOAT-MOVE/SINGLE and
  FLOAT-MOVE/DOUBLE that can handle moving from FR0 or any XMM
  register to any XMM register.
o Update the move vops appropriately.

sse2-c-call.lisp:
o Don't need to move FR0 to XMM0 anymore.  This was one source of the
  problem.  The compiler knows now to ask for a move from FR0 to some
  XMM register.
o Update comments.

vm.lisp:
o Correct printing of XMM registers.  Previously printed them as
  XMM8-15 but should have been XMM0-7.  (Mostly in trace files.)

compiler/x86/vm.lisp:
o Change *float-register-names* to be defparameter.
o Setup float-regs and def-random-reg-tns appropriately for x87 and
  sse2.

lisp/Darwin-os.c:
lisp/Linux-os.c:
o Conditionalize previous change for FEATURE_SSE2.

Carl's suggestion and define new SC numbers for the xmm registers
instead of overloading the x87 fpu registers and the xmm register
SC's.

bootfiles/20a/boot-2010-06-cross-x86.lisp:
o New file needed for cross-compiling this change.

code/x86-vm.lisp:
o Revert previous change.

compiler/x86/sse2-c-call.lisp:
o Use xmm0-tn instead of fr0-tn.  No functional change, but makes the
  code more readable.

compiler/x86/vm.lisp:
o Increase the number of float registers from 8 to 16 (8 more for SSE2
  registers).
o Define new xmm<n> registers
o Update the locations with the new sse2 SC locations for single-reg,
  double-reg, double-double-reg, complex-single-reg,
  complex-double-reg, and complex-double-double-reg storage classes.

lisp/Darwin-os.c:
o Revert previous change.
o Update os_sigcontext_fpu_reg to support the xmm registers.

lisp/Linux-os.c:
o Update os_sigcontext_fpu_reg to support the xmm registers.

the new -P option for build.sh to generate and update the po files
while building.

registers.  Adjust the base-char VOPs accordingly.  Lastly, define the
simple-string VOPs using the same macro used by all other partial word
array VOPs.

The merge is from the tag "double-double-irrat-end".  The
double-double branch is now obsolete.

The code should build without double-double support (tested on sparc)
as well as build with double-double support (tested also on sparc).

remove unnecessary conditionals.

Combine the fp-single-constant and fp-double-constant storage classes
together into the new fp-constant storage class, saving a storage
class.

making the x86 code more consistent with the other ports.
Remove the descriptor-stack SC.
Remove the old-fp-save-offset constant.

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.

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.
