Move the FPU save/restore stuff from os.h to arch.h
* 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.
