// Parameter for validation test fixtures.  The first string is a capability
// name that will begin the assembly under test, the second the remainder
// assembly, and the vector at the end determines whether the test expects
// success or failure.  See below for details and convenience methods to access
// each one.
//
// The assembly to test is composed from a variable top line and a fixed
// remainder.  The top line will be an OpCapability instruction, while the
// remainder will be some assembly text that succeeds or fails to assemble
// depending on which capability was chosen.  For instance, the following will
// succeed:
//
// OpCapability Pipes ; implies Kernel
// OpLifetimeStop %1 0 ; requires Kernel
//
// and the following will fail:
//
// OpCapability Kernel
// %1 = OpTypeNamedBarrier ; requires NamedBarrier
//
// So how does the test parameter capture which capabilities should cause
// success and which shouldn't?  The answer is in the last element: it's a
// vector of capabilities that make the remainder assembly succeed.  So if the
// first-line capability exists in that vector, success is expected; otherwise,
// failure is expected in the tests.
//
// We will use testing::Combine() to vary the first line: when we combine
// AllCapabilities() with a single remainder assembly, we generate enough test
// cases to try the assembly with every possible capability that could be
// declared. However, Combine() only produces tuples -- it cannot produce, say,
// a struct.  Therefore, this type must be a tuple.
