e0aa279fc8 Silly assertion. Forgot variable_ops instructions can have arbitrary number of 
operands.

d042dac8ab - Add getOperandConstraint() to TargetInstrDescriptor. 
- convertToThreeAddress() change to allow single two-address MI to be converted
  into one or more 3-address MIs.

of an M_PREDICATED instruction.

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.

0b8e4bca80 Add capability to scheduler to commute nodes for profit. 
If a two-address code whose first operand has uses below, it should be commuted
when possible.

6684ba101f Move isLoadFrom/StoreToStackSlot from MRegisterInfo to TargetInstrInfo, 
a far more logical place.  Other methods should also be moved if anyone
is interested. :)
