5e51979f90 1. Made things node-centric (from operand). 
2. Added node groups to handle flagged nodes.

3. Started weaning simple scheduling off existing emitter.

49117a5dcc these registers don't belong to any register classes, so don't mark them 
as callee save.  They can never be generated by the compiler.

2b7ab1f445 Refactor this a bit to move ParsingTemplateArgs to only apply to classes, 
not defs.

Implement support for forward definitions of classes.  This implements
TableGen/ForwardRef.td.

7c8efa3b9b now that tblgen is smarter, this pattern is not needed. Also, tblgen 
now inverts commuted versions of ANDC/ORC with the current .td file.

31a9d318a3 Teach tblgen to build permutations of instructions, so that the target author 
doesn't have to specify them manually.  It currently handles associativity,
e.g. knowing that (X*Y)+Z  also matches  X+(Y*Z)  and will be extended in
the future.

It is smart enough to not introduce duplicate patterns or patterns that can
never match.

cb09b023d3 Make the JIT default to the DAG isel instead of the pattern isel, like LLC. 
The Pattern isel has some strange memory corruption issues going on. :(

This should have been converted over anyway, but it got forgotten somehow
when switching to the dag isel.
