This is the follow-up for 46cef9bfdd.
After that change, VM's optimizer (canonicalization) removes
initializing stores which store null, even if they're overwriting the
result of another initializing store. This causes incorrect behavior
in cases like this:
class A {
int x = 3;
A() : x = null {}
}
To accomodate for this change in the VM's optimizer, bytecode generator
should elide duplicate stores, similarly to AST-based flow graph
builder.
Fixes language_2/field_parameter_test in AOT mode with bytecode.
