Shu-yu Guo 24af42e8a3 [test] Fix flag misconfig
--no-stress-flush-bytecode doesn't exist and should be
--no-stress-flush-code. Not supressing it means a tester could pass
--stress-flush-code and --no-flush-bytecode, which are contradictory and
will assert.

// These tests do not work well if this script is run more than once (e.g.

// Flags: --no-stress-flush-code --no-flush-bytecode
