Add insn types for fusion pairs

Add insn types for fusion pairs

This adds new values for insn attr type for p10 fusion. The genfusion.pl
script is modified to use them, and fusion.md regenerated to capture
the new patterns. There are also some formatting only changes to
fusion.md that apparently weren't captured after a previous commit
of genfusion.pl.
