Alexander Markov 63e170a242 [vm/compiler] More consistent handling of inputs of IL instructions 
This change removes duplicate management of inputs in variadic
IL instructions by introducing VariadicDefinition and
VariadicDefinitionWithEmbeddedInputs base classes.

TemplateInstruction and TemplateDefinition are used in more
places where appropriate.

Number of inputs no longer depends on the values of the inputs
(DropTempsInstr and AllocateObjectInstr).

This change also prepares IL for the future implementation of binary
serialization/deserialization in the following ways:
* Environment now holds Function and not ParsedFunction
  (which are not going to be serialized).
* Instructions no longer keep Zone* pointer (it's redundant).
* NativeCallInstr keeps references to handles instead of pointers.

TEST=ci (pure refactoring)

Dart VM Compilation Pipeline

This folder contains Dart VM compilation pipeline.

Compilation pipeline is mainly responsible for converting AST or Kernel AST into IL flow graphs and then generating native code from IL.

It has the following structure:

Directory What goes there
assembler/ Assemblers and disassemblers
backend/ IL based compilation backend: optimization passes and architecture specific code generation rules
frontend/ Frontends responsible for converting AST into IL
jit/ JIT specific passes and compilation pipeline entry points
aot/ AOT specific passes and compilation pipeline entry points
. Shared code or code without clear designation.

Currently there are no layering restrictions and components from different subfolders can reference each other.
