Evan Cheng 15a16def6e Add a hybrid bottom up scheduler that reduce register usage while avoiding ...

pipeline stall. It's useful for targets like ARM cortex-a8. NEON has a lot
of long latency instructions so a strict register pressure reduction
scheduler does not work well.
Early experiments show this speeds up some NEON loops by over 30%.
