* i387-tdep.h (i387_print_float_info): New prototype.

Browse Source 
* i387-tdep.c (print_i387_value, print_i387_ext,
print_i387_status_word, print_i387_control_word): Add `struct
ui_file *' argument and use it for output.
(i387_print_float_info): Renamed from i387_float_info.  Add
`struct gdbarch *' and `struct ui_file *' arguments and use the
latter for output.
* i386-tdep.c: Include "i387-tdep.h".
(i386_gdbarch_init): Set print_float_info.
* config/i386/tm-i386.h (i387_float_info): Remove prototype.
(FLOAT_INFO): Remove define.
