Check type for legality before forming a select from loads.

Sorry for the lack of a test case.  I tried writing one for i386 as i know selects are illegal on this target, but they are actually considered legal by isel and expanded later.

I can't see any targets to trigger this, but checking for the legality of a node before forming it is general goodness.
