Vyacheslav Egorov cc35ba4a1e [vm] Split _List&_GrowableList []= into checked and unchecked parts 
This allows us to avoid going into runtime even if strong mode is
enabled: type checking is handled in the []= operator itself and
_setIndexed does not need to check types and thus can be intrinsified.

This CL also removes inline type checking done in ia32 version,
not other platform had it.

# Performance Impact

Mostly noticable on Dart v2 AOT configuration where AOT compiler
did not inline []=:

Alexander Markov 48f76f6b41 [VM, Compiler] Refactor and reuse token kind recognition 
This CL moves method token kind recognition from kernel_to_il.cc
to method_recognizer.cc and reuses it in aot_call_specializer.cc.
Also, similar code in il.cc (TryFastPathSmiOp) is refactored to use
token kind.

Vyacheslav Egorov 8a179fb953 [VM, Compiler] Move compiler to a separate folder. 
New folder structure (nested under vm/):

- compiler/
-   jit/         - JIT specific code
-   aot/         - AOT specific code
-   backend/     - all middle-end and back-end code (IL, flow graph)
-   assembler/   - assemblers and disassemblers
-   frontend/    - front ends (AST -> IL, Kernel -> IL)

compiler/README.md would be the documentation root for the compiler
pipeline
