497e752655 Add a DebugLoc argument to TargetInstrInfo::copyRegToReg, so that it 
doesn't have to guess.

FU per CPU arch to 32 per intinerary allowing precise modelling of quite

a0f855157e 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.

4c043c50fd Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field. 
When a target instruction wants to set target-specific flags, it should simply
set bits in the TSFlags bit vector defined in the Instruction TableGen class.

This works well because TableGen resolves member references late:

class I : Instruction {
  AddrMode AM = AddrModeNone;
  let TSFlags{3-0} = AM.Value;
}

let AM = AddrMode4 in
def ADD : I;

TSFlags gets the expected bits from AddrMode4 in this example.

3eaaa7bb6c Momentous day: remove the "O" member from AsmPrinter. Now all 
"asm printering" happens through MCStreamer.  This also 
Streamerizes PIC16 debug info, which escaped my attention.

This removes a leak from LLVMTargetMachine of the 'legacy'
output stream.

e7538fa303 rearrange MCContext ownership. Before LLVMTargetMachine created it 
and passing off ownership to AsmPrinter.  Now MachineModuleInfo
creates it and owns it by value.  This allows us to use MCSymbols
more consistently throughout the rest of the code generator, and
simplifies a bit of code.  This also allows MachineFunction to 
keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.

f328c5334f Change the Value argument to eliminateFrameIndex to a type-tagged value. This 
is preparatory to having PEI's scavenged frame index value reuse logic
properly distinguish types of frame values (e.g., whether the value is
stack-pointer relative or frame-pointer relative).

No functionality change.

1707a88a2c Sink InstructionSelect() out of each target into SDISel, and rename it 
DoInstructionSelection.  Inline "SelectRoot" into it from DAGISelHeader.
Sink some other stuff out of DAGISelHeader into SDISel.

Eliminate the various 'Indent' stuff from various targets, which dates
to when isel was recursive.

edf1e280a2 rejigger the world so that EmitInstruction prints the \n at
