    [wasm] Add tests for grow_memory inside functions · d74ec7ef
    Enrico Bacis authored
    This CL introduces 6 tests that verify that the effects of a grow_memory
    instruction executed inside a function are visible also from the caller of
    the function.
    
    The tests verify that:
    
     * the current_memory instruction returns the correct value after
     returning from a function that grew memory;
    
     * accessing a memory page that has been created inside a function does
     not trap in the caller;
    
     * when a function grows the memory and then store something in the grown
     memory, the caller always reads from the grown memory. This checks that
     the memory start address gets updated in the caller (the memory buffer
     could in fact be relocated by the grow_memory instruction).
    
    These tests are implemented for direct and indirect function calls.
