With PPC CR bit registers, handle int_to_fp on older cores
On cores without fpcvt support, we cannot promote int_to_fp i1 operations,
because there is nothing to promote them to. The most straightforward
implementation of this uses a select to choose between the two possible
resulting floating-point values (and that's what is done here).
