When looking for an exception handler, PC corresponding to a return
address is used (e.g. it is pointing to the next instruction).
This CL adjusts start and end offsets of bytecode try blocks in
PcDescriptors accordingly.

Now, instead of generating Symbol constant pool entries, bytecode generator
uses kernel-to-kernel constant evaluator to evaluate symbol literals.

As TypeArguments == null means 'vector of all dynamic', VM uses special
object (Object::empty_type_arguments()) to indicate absence of
_Closure._delayed_type_arguments.
This CL corrects bytecode to use Object::empty_type_arguments() (via new
constant pool entry EmptyTypeArguments) to initialize
_Closure._delayed_type_arguments when allocating a closure.

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.

As the interpreter matures it will hopefully be merged into the regular
jit configuration, but for now we make a separate configuration for it.

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.

Before this change, ConstantClosureFunction was holding a clone of original
FunctionNode without body (in order to omit body during serialization).
It is not correct: original FunctionNode, which is used to generate
closure's bytecode may reference original type parameters and those
type parameters could be used in types written into constant pool.
A cloned FunctionNode has its own cloned copies of type parameters
and it does not provide a sufficient serialization/deserialization context.
This resulted in 'Type parameter T is not indexed' errors.
This CL fixes this problem by removing cloning. In order to avoid
serialization of the FunctionNode body, body is temporarily dropped
while writing ConstantClosureFunction.
Also, this CL fixes type finalization of signature types of closure functions
read from bytecode. If signature type is not finalized, VM crashes with
'../../runtime/vm/object.cc: 18580: error: expected: IsFinalized()'.

This change continues refactoring to split kernel_binary_flowgraph and
kernel_to_il and move out parts which have no dependencies on flow graph
construction.
Bytecode reading is moved to a separate file bytecode_reader{.h, .cc}.
Metadata helpers, TypeTranslator, ActiveClass and other Active* are moved
to kernel_translation_helper.
Removed dependency of ICData tags on IL Instruction tags, so ICData objects
can be created by bytecode reader without depending on IL.
Unused AlternativeScriptScope is removed.
