Chris Lattner a10fff51d9 Rename SSARegMap -> MachineRegisterInfo in keeping with the idea
that "machine" classes are used to represent the current state of
the code being compiled.  Given this expanded name, we can start 
moving other stuff into it.  For now, move the UsedPhysRegs and
LiveIn/LoveOuts vectors from MachineFunction into it.

Update all the clients to match.

This also reduces some needless #includes, such as MachineModuleInfo
from MachineFunction.

Chris Lattner a5bb370aa4 Add new shorter predicates for testing machine operands for various types:
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

Chris Lattner 6005589faf More cleanups for MachineOperand:
- Eliminate the static "print" method for operands, moving it
    into MachineOperand::print.
  - Change various set* methods for register flags to take a bool
    for the value to set it to.  Remove unset* methods.
  - Group methods more logically by operand flavor in MachineOperand.h

Chris Lattner c98c0e57eb MachineOperand:
- Add getParent() accessors.
  - Move SubReg out of the AuxInfo union, to make way for future changes.
  - Remove the getImmedValue/setImmedValue methods.
  - in some MachineOperand::Create* methods, stop initializing fields that are dead.

MachineInstr:
  - Delete one copy of the MachineInstr printing code, now there is only one dump
    format and one copy of the code.
  - Make MachineOperand use the parent field to get info about preg register names if
    no target info is otherwise available.
  - Move def/use/kill/dead flag printing to the machineoperand printer, so they are
    always printed for an operand.

Evan Cheng 7f02cfa599 Clean up sub-register implementation by moving subReg information back to
MachineOperand auxInfo. Previous clunky implementation uses an external map
to track sub-register uses. That works because register allocator uses
a new virtual register for each spilled use. With interval splitting (coming
soon), we may have multiple uses of the same register some of which are
of using different sub-registers from others. It's too fragile to constantly
update the information.

Evan Cheng aa2d6ef81d EXTRACT_SUBREG coalescing support. The coalescer now treats EXTRACT_SUBREG like
(almost) a register copy. However, it always coalesced to the register of the
RHS (the super-register). All uses of the result of a EXTRACT_SUBREG are sub-
register uses which adds subtle complications to load folding, spiller rewrite,
etc.

Chris Lattner 539df43e4b setOperand should not zap the operand list or add implicit operands to an
instruction.  Doing so breaks the FP stackifier, the alpha branch selector
the sparc fpmover.

Evan Cheng 77af6ac5e8 - Let MachineInstr ctors add implicit def and use operands. Other operands
will be inserted before these operands. If the opcode changes (by
  setOpcode), the implicit operands are updated as well.
- Added IsKill, IsDead fields to MachineOperand in preparation for changes
  that move kill / dead info to MachineInstr's.

Evan Cheng 55772ccfd6 Instructions with variable operands (variable_ops) can have a number required
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.
