0b8e4bca80 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.

cb2a0f392c Refactor scheduler code. Move register-reduction list scheduler to a 
separate file. Added an initial implementation of top-down register pressure
reduction list scheduler.

7ed816f900 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.

a0769e790e Hoist the HazardRecognizer out of the ScheduleDAGList.cpp file to where 
targets can implement them.  Make the top-down scheduler non-g5-specific.

168b8c5b29 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.
