This CL introduces 4 test that verify that the effects of a grow_memory
instruction executed in a function invoked inside a loop are visible
also when the loop is over. This is needed because the
AnalyzeLoopAssignment method in function-body-decoder.cc is creating Phi
nodes only for variables assigned inside the loop. The test cases
introduced by this CL verify that the mem_size and mem_start variables
are always correct.
The tests verify the output of the current_memory instruction and the
result of loading a variable stored in the grown memory inside the
loop in the following cases:
* the memory is grown in a directly called function inside a loop;
* the memory is grown in an indirectly called function inside a loop.

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.
