// Tests that gen_kernel is able to produce dill file with both bytecode
// and AST in AOT mode, and gen_snapshot is able to consume them.
// Two test cases are only different in number of entry points, so
// obfuscation prohibitions metadata has different size, causing
// different alignment of bytecode metadata.
