This addresses #4307. For the static API we generate 100 arbitrary test cases at build time, each of which includes 0-5 parameter types, a result type, and a WAT fragment containing an imported function and an exported function. The exported function calls the imported function, which is implemented by the host. At runtime, the fuzz test selects a test case at random and feeds it zero or more sets of arbitrary parameters and results, checking that values which flow host-to-guest and guest-to-host make the transition unchanged. The fuzz test for the dynamic API follows a similar pattern, the only difference being that test cases are generated at runtime. Signed-off-by: Joel Dice <joel.dice@fermyon.com>
