[SelectionDAGBuilder] Simplify loop in visitSelect back to how it was before r255558.

Browse Source 
This code was changed to accomodate fp128 being softened to itself
during type legalization on x86-64. This was done in order to create
libcalls while having fp128 as a legal type. We're now doing the
libcall creation during LegalizeDAG and the type legalization changes
to enable the old behavior have been removed. So this change to
SelectionDAGBuilder is no longer needed.
