Evan Cheng 1880f8db02 No need to keep track of top and bottom nodes in a group since the vector is 
already in order. Thanks Jim for pointing it out.

Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

Evan Cheng a6eff8a432 If scheduler choice is the default (-sched=default), use target scheduling 
preference to determine which scheduler to use. SchedulingForLatency ==
Breadth first; SchedulingForRegPressure == bottom up register reduction list
scheduler.
