inlining function, then increase the stack protection level on the inlining
function.

Introduce two new "add" intrinsics. These return the sum plus a bit indicating
...
that an overflow/carry occured. These are converted into ISD::[SU]ADDO nodes,
which are lowered in a target-independent way into something sane. Eventually,
each target can implement their own method of checking the overflow/carry flags.

Experimental post-pass scheduling support. Post-pass scheduling
...
is currently off by default, and can be enabled with
-disable-post-RA-scheduler=false.
This doesn't have a significant impact on most code yet because it doesn't
yet do anything to address anti-dependencies and it doesn't attempt to
disambiguate memory references. Also, several popular targets
don't have pipeline descriptions yet.
The majority of the changes here are splitting the SelectionDAG-specific
code out of ScheduleDAG, so that ScheduleDAG can be moved to
libLLVMCodeGen.a. The interface between ScheduleDAG-using code and
the rest of the scheduling code is somewhat rough and will evolve.
