Prior to this CL the return type of any constructor function was
always void. According to the specification §9.3 the return type of a
constructor function ought to be its enclosing class.

If a field is initialized with null (either explicitly or implicitly),
field store can be omitted in bytecode. In such case, bytecode should
still convey the information about this initialization to VM for
field guards to work correctly.

These bytecode instructions are added in order to shrink constant pools
and reduce time spent for reading constant pool entries.

Fix for failing test language_2/final_field_initialization_order_test.
Bytecode generator was incorrectly omitting field initializer if
constructor also has initializer for that field.

Number of checked arguments is corrected in ICData objects created when
reading bytecode, both for instance and static calls.
InstanceCall1 and InstanceCall2 bytecode instructions are replaced with
InstanceCall which works for any number of checked arguments. This makes
decision on number of checked arguments internal to VM and it is no longer
exposed to bytecode.

Constant pool:
* Field constant pool entry is renamed to StaticField
* FieldOffset constant pool entry is replaced with InstanceField.
InstanceField occupies 2 slots for field offset and field object.
* ContextOffset constant pool entry is removed.
* TypeArgumentsFieldOffset is renamed to TypeArgumentsField
Bytecodes:
* LoadFieldTOS and StoreFieldTOS require InstanceField entry.
* New bytecodes added: LoadContextParent, StoreContextParent,
LoadContextVar, StoreContextVar, LoadTypeArgumentsField.
This CL is a preparation for compilation of bytecodes related
to instance field accesses.

Values of static fields with trivial initializers are pre-initialized
at load time, so such static fields do not have implicit getters.
Bytecode generator is fixed to treat double literal initializers as trivial
and avoid calling getters for such fields.
Also, this CL disables bytecode generation for static fields with trivial
initializers as their bytecode is not used.
