* Use new FunctionFrameInfo object to manage stack slots instead of doing
  it directly
* Adjust to new MRegisterInfo API
* Don't take a TM as a ctor argument
* Don't keep track of which callee saved registers are modified
* Don't emit prolog/epilog code or spill/restore code for callee saved regs
* Use new allocation_order_begin/end iterators to simplify dramatically the
  logic for picking registers to allocate
* Machine PHI nodes can no longer contain constant arguments

* Use a bitvector to keep track of registers used instead of a set
* Fix problem where explicitly referenced registers would be added to
  regsused set and never removed

* most pass ctors no longer take TM arguments
* New prolog/epilog insertion pass

llvm-svn: 5187

* Include contents of X86RegisterClasses.cpp into here
* Adjustments to register api to work with new frame manager
* Eliminate moveImm2Reg, getFramePointer, and getStackPointer
* Cleanup and simplify prolog/epilog code generation
* Prolog/epilog are MUCH more efficient now.

* Remove some size suffixes [bwl]
* Add new ADJCALLSTACKDOWN & ADJCALLSTACKUP pseudo instrs
* Call instructions are M_CALL not M_BRANCH!
* Disable push and pop instructions
* Add new ANDri32 instr

llvm-svn: 5183

llvm-svn: 5182

* New createPrologEpilogCodeInserter() function

llvm-svn: 5181

* Don't take a TM as a ctor parameter
* Print [X - Y] instead of [X + -Y] when possible

llvm-svn: 5180

* ctor doesn't take TM argument
* handle direct ESP references correctly!

llvm-svn: 5179

  fixed size allocas
* Revamp call emission to work with new frame manager

llvm-svn: 5178

* Constant pool and frame info is no longer directly in MachineFunction

llvm-svn: 5177

* Move some sparc specific code here from Target files

* Constpool & frame info is no longer directly in MachineFunction

llvm-svn: 5174

llvm-svn: 5173

* Frame information is now stuck in MachineFunctionInfo instead of directly
  in MachineFunction.
* Don't require a TM as an argument to the ctor

llvm-svn: 5172

* Changes because frame info is not in MachineFunction directly anymore

llvm-svn: 5171

* rename MachineFrameInfo to TargetFrameInfo

llvm-svn: 5170

target specific information.  Rename MachineFrameInfo to TargetFrameInfo

llvm-svn: 5168

* Add comments
* Add a new allocation_order iterator for register classes which targets may
  use to control the register order and available registers based on properties
  of the function being compiled.
* Remove access to FP and SP registers
* Add new callframe setup opcode support
* Eliminate moveImm2Reg method
* Revamp frame offset handling and prolog/epilog code generation
