Vyacheslav Egorov d290d8ecf4 [vm] Detect and expand calls through getters in AOT call specializer. 
If we know that receiver is a subclass of a certain type and that this
type has accessor get:m then call o.m(...) is guaranteed to be an
invocation through a getter. Such invocations are executed most
efficiently when expanded into o.get:m().call(...).

Source based pipeline handles this case (at least for invocations on
`this`) directly in the parser, but Kernel based graph builder does not
have this sort of special case.

Instead of teaching Kernel flow graph builder to specially handle
invocations on `this` we teach AOT call specializer to specially handle
all invocations where receiver is known to be a subclass of certain
class. Such optimization is more generic and handles things that
previously were not handled by the optimization.

AOT compiler also has heuristics for injecting field dispatchers into
classes but these heuristics only handle fields of function type and
don't work for fields like `Function f` or `var f`.

Improves ParserCombinators benchmark by 4x.

This relands eea2c168f9 with a fix.
