85e02e9340 Rename CreateRegForValue to CreateReg, and change its argument 
from a Value to a Type, because it doesn't actually care about
the Value.

d16aa541af SelectionDAG shouldn't have a FunctionLoweringInfo member. RegsForValue 
shouldn't have a TargetLoweringInfo member. And FunctionLoweringInfo::set
doesn't needs its EnableFastISel argument.

ec74444d3e Remove the code for special-casing byval for fast-isel. SelectionDAG 
handles argument lowering anyway, so there's no need for special
casing here.

6e822459ed Replace r102368 with code that's less fragile. This creates DBG_VALUE instructions for function arguments early and insert them after instruction selection is done.

SelectionDAG-specific.

21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

7258dcd77f Revert 101465, it broke internal OpenGL testing. 
Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

f375520f7b reapply r101434 
with a fix for self-hosting

rotate CallInst operands, i.e. move callee to the back
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

8ebcbe949a Pull utility routines with no SelectionDAG dependence out of 
SelectionDAGBuilder. FunctionLoweringInfo isn't an ideal place for
them to live, but it's better than SelectionDAGBuilder for now.

b06015aa69 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

general lowering logic from SelectionDAG-specific lowering logic.
