Move floating-point code to new function in i387-tdep.c. * i387-tdep.c (i387_register_to_value, i387_value_to_register): New functions containing code moved here from i386-tdep.c. * i387-tdep.h: Add opaque declaration for `struct type'. (i387_register_to_value, i387_value_to_register): New prototypes. * x86-64-tdep.c (x86_64_convert_register_p): New function. (x86_64_init_abi): Set convert_register_p, register_to_value and value_to_register here.
