Ugly hack! Add helper functions InsertInFlightSetEntry and

RemoveInFlightSetEntry. They are used in place of direct set operators to
reduce instruction selection function stack size.

Don't require src/dst patterns to be able to fully resolve their types,
...
because information about one can help refine the other. This allows us to
write:
def : Pat<(i32 (extload xaddr:$src, i8)),
(LBZX xaddr:$src)>;
as:
def : Pat<(extload xaddr:$src, i8),
(LBZX xaddr:$src)>;
because tblgen knows LBZX returns i32.

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.
