The hardcoded constant caused a problem for the wasm fuzzer because when the maximum memory was allocated in a test case, clusterfuzz ran out of memory. with the command line flag we can set a lower limit for the fuzzer. The flag has the value of the constant as its default value, so that for everything but the fuzzers nothing should change.
