 //     (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.
