13d41b9d72 Add capability to scheduler to commute nodes for profit.
If a two-address code whose first operand has uses below, it should be commuted
when possible.

e165a78551 Refactor scheduler code. Move register-reduction list scheduler to a
separate file. Added an initial implementation of top-down register pressure
reduction list scheduler.

37efe67645 JumpTable support! What this represents is working asm and jit support for
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

37e30cf736 Hoist the HazardRecognizer out of the ScheduleDAGList.cpp file to where
targets can implement them.  Make the top-down scheduler non-g5-specific.

already in order. Thanks Jim for pointing it out.
