5d5c93f659 Add a TargetInstrDescriptor flag to mark an instruction as "re-materializable". 
It means the instruction can be easily re-materialized at any point. e.g.
constant generation, load from constantpool.

  into one or more 3-address MIs.

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.
