4fc8a5c0b5 Make SDNode constructors take a DebugLoc always. 
Adjust derived classes to pass UnknownLoc where
a DebugLoc does not make sense.  Pick one of
DebugLoc and non-DebugLoc variants to survive
for all such classes.

a259483aae Get rid of the last non-DebugLoc versions of getNode! 
Many targets build placeholder nodes for special operands, e.g.
GlobalBaseReg on X86 and PPC for the PIC base.  There's no
sensible way to associate debug info with these.  I've left
them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. 
I'm not too happy about this but don't see a good improvement;
I considered adding a getPseudoOperand or something, but it
seems to me that'll just make it harder to read.

1580ab6b7f Remove more non-DebugLoc getNode variants. Use 
getCALLSEQ_{END,START} to permit passing no DebugLoc
there.  UNDEF doesn't logically have DebugLoc; add
getUNDEF to encapsulate this.

c097f9628e Rename SelectionDAGISel::Schedule to 
SelectionDAGISel::CreateScheduler, and make it just create the
scheduler. Leave running the scheduler to the higher-level code.
This makes the higher-level code a little more explicit and
easier to follow, and will help enable some future refactoring.
