Subject: [PATCH] [mlir][TblGen] `get...Mutable` returns `OpOperand &` for
single operands
The TableGen code generator now generates C++ code that returns a single `OpOperand &` for `get...Mutable` of operands that are not variadic and not optional. `OpOperand::set`/`assign` can be used to set a value (same as `MutableOperandRange::assign`). It is safer than `MutableOperandRange` only single values (and no longer `ValueRange`) can be assigned.
E.g.:
```
// Before: Assign multiple values to non-variadic operand (forbidden, but
// compiles).
// After: Compilation error.
extractSliceOp.getSourceMutable().assign({v1, v2});
```
