This allows the results of a ComplexPattern check to be distributed to separate
named Operands, instead of the current system where all results must apply (and
match perfectly) with a single Operand.
For example, if "some_addrmode" is a ComplexPattern producing two results, you
can write:
def : Pat<(load (some_addrmode GPR64:$base, imm:$offset)),
(INST GPR64:$base, imm:$offset)>;
This should allow neater instruction definitions in TableGen that don't put all
possible aspects of addressing into a single operand, but are still usable with
relatively simple C++ CodeGen idioms.
