i386_register_convertible, i386_register_convert_to_virtual,
i386_register_comvert_to_raw): Use FP_REGNUM_P and SSE_REGNUM_P
instead of IS_FP_REGNUM and IS_SSE_REGNUM.
(i386_gdbarch_init): Fix comment.  Add comments on calls that set
sp_regnum, fp_regnum, pc_regnum, ps_regnum and fp0_regnum.
Don't set push_arguments twice.
