80a4f169b4 Now that we have getCalleeSaveRegClasses() info, use it to pass the register 
class into the spill/reload methods.  Targets can now rely on that argument.

0a37960d32 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.

c3bec0e401 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.

e46e17b7fb 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.

f13befb456 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.
