rs6000: Improve truncifsf2

The current implementation leaves an unnecessary register move.  It is
easier to just expand things in the expander already.  This patch does
that.

* config/rs6000/rs6000.md (trunc<mode>sf2): Expand truncates of
double-double modes to SFmode directly directly.
(trunc<mode>sf2_fprs): Delete.
