//     INTENDED_AT_COMPILE_AND_EXECUTE: set the dimension at compile
//     (addOperand) time to INTENDED_SIZE, use same size at execution
//     (setInput/setOutput) time. This should always work.
//
//     INTENDED_AT_COMPILE_NOT_SET_AT_EXECUTE: set the dimension at compile
//     (addOperand) time to INTENDED_SIZE, give no size at execution time.
//     This should always work.
//
//     UNKNOWN_AT_COMPILE_INTENDED_AT_EXECUTE: don't set the dimension at
//     compile (addOperand) time, use INTENDED_SIZE at execute
//     (setInput/setOutput) time. Note for constants, this just means using an
//     unknown dimension at addOperand as there is no type parameter to
//     setOperandValue. This should work for inputs and outputs and give an
//     error for constants at compile time.
//
//     UNKNOWN_AT_COMPILE_OTHER_AT_EXECUTE: don't set the dimension at compile
//     (addOperand) time, use OTHER_SIZE at execute (setInput/setOutput) time.
//     This should give an error at execute time (as the constant value will
//     have a different size).
//
// All relevant combinations of the basic scenarios are then iterated over in
// TestAll. Note that we don't want to just use googletest's parametrized tests (TEST_P) as
// the 16k combinations generated too many lines of output for the test
// infrastructure to handle correctly. However, running all 16k in one test
// makes the ASAN version take so long that the automatic test runner things the
// command has become unresponsinve, so we split on the first level.
