Verbose eflags on i386/x86-64

The traditional (note that I'm not saying better :-) way of doing this 
is to implement custom versions of the multi-arch functions 
do_registers_info() and/or print_float_info().

As for changing eflags's type, do you need a print function or can the 
type be changed in a way that, when printed using existing code, has the 
effect you want?

I'd have a look at the i386 code.
