Profiler does not allow 2 distinct Bytecode objects to use the same
range of bytecode, as it needs to map PC to a Bytecode unambiguously.
So this change removes reuse of the field initializer bytecodes for
a field getter (in case of const fields).

dart2bytecode can optionally add source position information
(including line starts) to the generated bytecode
(when '--bytecode-options=source-positions' flag is specified).
If bytecode has source positions, they are now shown in stack traces
involving interpreter frames.

* Never unbox fields loaded from bytecode as interpreter works with
boxed fields only.
* Ensure classes are allocate-finalized in AllocateObject
runtime entry as interpreter may allocate instances of certain
built-in classes (such as _Closure, _Double etc) without prior
allocate-finalization.
* Fix type arguments vector in constant instances when class doesn't
have type parameters but extends a generic class (so its instances
have type arguments vector).

When creating function types, VM takes number of parent function type
arguments into account. So function types with distinct number of
parent function type arguments should not be merged in the bytecode
object table and should be represented as distinct types.

When reading function types from bytecode, number of implicit
parameters should be set in the FunctionType.
Capture variable holding a local function when local function
invocation happens from a different function scope.
Also remove debug prints from bytecode reader.
