Assign ordering to SDNodes in PromoteNode. Also fixing a subtle bug where BSWAP
...
was using "Tmp1" in the first getNode call instead of Node->getOperand(0).

Add more plumbing. This time in the LowerArguments and "get" functions which
...
return partial registers. This affected the back-end lowering code some.
Also patch up some places I missed before in the "get" functions.

Changes from review:
...
- Move DisableScheduling flag into TargetOption.h
- Move SDNodeOrdering into its own header file. Give it a minimal interface that
doesn't conflate construction with storage.
- Move assigning the ordering into the SelectionDAGBuilder.
This isn't used yet, so there should be no functional changes.

Handle ARM inline asm "w" constraints with 64-bit ("d") registers.

The change in SelectionDAGBuilder is needed to allow using bitcasts to convert
between f64 (the default type for ARM "d" registers) and 64-bit Neon vector
types. Radar 7457110.

Initial work on disabling the scheduler. This is a work in progress, and this
...
stuff isn't used just yet.
We want to model the GCC `-fno-schedule-insns' and `-fno-schedule-insns2'
flags. The hypothesis is that the people who use these flags know what they are
doing, and have hand-optimized the C code to reduce latencies and other
conflicts.
The idea behind our scheme to turn off scheduling is to create a map "on the
side" during DAG generation. It will order the nodes by how they appeared in the
code. This map is then used during scheduling to get the ordering.
