  Log Message:
  -----------
  [llvm][PassSupport] don't require passes to be default constructible

Quite a few passes are not default constructible. In order to properly
support -{start|stop}-{before|after}= for these passes, we would like to
continue to use INITIALIZE_PASS, but not necessarily provide a default
constructor.

Delete the default constructors of classes derived from
SelectionDAGISel.
