46e4658c95 eliminate a copy of the machineoperand printing stuff. Keep the copy that
knows how to print offsets.

fd33cb316f 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.

d11cd4a095 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.

isRegister, isImmediate, and isMachineBasicBlock, which are equivalent,

31f45746ad 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.

7cabf9d02c - 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.

07d8ccec50 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.
