Lei Zhang 13c6e419ca Add support for AttrSizedOperandSegments/AttrSizedResultSegments ... Certain operations can have multiple variadic operands and their size relationship is not always known statically. For such cases, we need a per-op-instance specification to divide the operands into logical groups or segments. This can be modeled by attributes. This CL introduces C++ trait AttrSizedOperandSegments for operands and AttrSizedResultSegments for results. The C++ trait just guarantees such size attribute has the correct type (1D vector) and values (non-negative), etc. It serves as the basis for ODS sugaring that with ODS argument declarations we can further verify the number of elements match the number of ODS-declared operands and we can generate handy getter methods.
