Evan Cheng 8d3af5e7d0 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.

If a two-address code whose first operand has uses below, it should be commuted
when possible.

a far more logical place.  Other methods should also be moved if anyone
is interested. :)

Brian Gaeke 1b4aeb5cec As it happens, none of these TargetInstrInfo methods which are only 
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global

(They're mostly used as helper functions for SparcV9InstrSelection.)
