81b441151f Separate code that modifies control flow from code that adds instruction to 
basic blocks.

439661395f Introduce MCCodeGenInfo, which keeps information that can affect codegen 
(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

0e6a052331 Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo down 
to MCRegisterInfo. Also initialize the mapping at construction time.

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

0d7d0b5cb7 Set mayLoad or mayStore flags for SC and LL in order to prevent LICM from 
moving them out of the loop. Previously, stores and loads to a stack frame
object were inserted to accomplish this. Remove the code that was needed to do
this. Patch by Sasa Stankovic.

59ee62d241 - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo 
and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.

ffc0e73046 Change createAsmParser to take a MCSubtargetInfo instead of triple, 
CPU, and feature string. Parsing some asm directives can change
subtarget state (e.g. .code 16) and it must be reflected in other
modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance
must be shared.

ebdeeab812 Eliminate asm parser's dependency on TargetMachine: 
- Each target asm parser now creates its own MCSubtatgetInfo (if needed).
- Changed AssemblerPredicate to take subtarget features which tablegen uses
  to generate asm matcher subtarget feature queries. e.g.
  "ModeThumb,FeatureThumb2" is translated to
  "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0".

276365dd4b Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name to 
be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!

a347f85dbe Starting to refactor Target to separate out code that's needed to fully describe 
target machine from those that are only needed by codegen. The goal is to
sink the essential target description into MC layer so we can start building
MC based tools without needing to link in the entire codegen.

First step is to refactor TargetRegisterInfo. This patch added a base class
MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to
separate register description from the rest of the stuff.

f28987b76e Use set operations instead of plain lists to enumerate register classes. 
This simplifies many of the target description files since it is common
for register classes to be related or contain sequences of numbered
registers.

I have verified that this doesn't change the files generated by TableGen
for ARM and X86. It alters the allocation order of MBlaze GPR and Mips
FGR32 registers, but I believe the change is benign.

2a9d1ca9c2 Remove custom allocation order boilerplate that is no longer needed. 
The register allocators automatically filter out reserved registers and
place the callee saved registers last in the allocation order, so custom
methods are no longer necessary just for that.

Some targets still use custom allocation orders:

ARM/Thumb: The high registers are removed from GPR in thumb mode. The
NEON allocation orders prefer to use non-VFP2 registers first.

X86: The GR8 classes omit AH-DH in x86-64 mode to avoid REX trouble.

SystemZ: Some of the allocation orders are omitting R12 aliases without
explanation. I don't understand this target well enough to fix that. It
looks like all the boilerplate could be removed by reserving the right
registers.

- cfi directives are not inserted at the right location or in the right order.
- The source MachineLocation for the cfi directive that changes the cfa register
  to $fp should be MachineLocation::VirtualFP.
- A PROLOG_LABEL that marks the beginning of cfi_offset directives for
  callee-saved register is emitted even when no callee-saved registers are
  saved.
- When a callee-saved double precision register is saved, two cfi_offset
  directives, one for each of the paired single precision registers, should be
  emitted.

69c19f7316 Change StackDirection from StackGrowsUp to StackGrowsDown. 
The following improvements are accomplished as a result of applying this patch:
- Fixed frame objects' offsets (relative to either the virtual frame pointer or
  the stack pointer) are set before instruction selection is completed. There is
  no need to wait until Prologue/Epilogue Insertion is run to set them.
- Calculation of final offsets of fixed frame objects is straightforward. It is
  no longer necessary to assign negative offsets to fixed objects for incoming
  arguments in order to distinguish them from the others.
- Since a fixed object has its relative offset set during instruction
  selection, there is no need to conservatively set its alignment to 4.
- It is no longer necessary to reorder non-fixed frame objects in 
  MipsFrameLowering::adjustMipsStackFrame.
