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.
