This is the next step towards preventing compiler from directly peeking
into runtime and instead interact with runtime through a well defined
surface.
This CL decouples the hand-written intrinsifier code from the runtime:
* the intrinsifier is split up into a GraphIntrinsifier and AsmIntrinsifier
* the recognized methods list is moved to a separate .h file
* all intrinsifier code is moved into dart::compiler namespace
* the AsmIntrinsifier is only interacting with RT through runtime_api.h

Fix some types of base objects in the V8 snapshot profile output.
Rename ICData::ic_data_ to entries_ as it does not point to an ICData.

This is the next step towards preventing compiler from directly peeking
into runtime and instead interact with runtime through a well defined
surface.
This CL decouples the hand-written stub codes from the runtime. The
target architecture dependent stubs are moved to
dart::compiler::StubCodeCompiler which use dart::compiler::target:*
for accessing any runtime related code.
The generation of type testing stubs is moved to separate files for the
time being.

This is due to how Windows destroys objects as destroyed objects have
their vtables reset to the vtable of the base class. If this happens
when an isolate hasn't finished shutting down and a virtual function
which is overriding a pure virtual function from the base class is
called, _purecall() is invoked and attempts to call exit() again which
leads to a deadlock.
See issue #35855 for more details.

This is the next step towards preventing compiler from directly peeking
into runtime and instead interact with runtime through a well defined
surface. The goal of the refactoring to locate all places where compiler
accesses some runtime information and partion those accesses into two
categories:
- creating objects in the host runtime (e.g. allocating strings, numbers, etc)
during compilation;
- accessing properties of the target runtime (e.g. offsets of fields) to
embed those into the generated code;
This change introduces dart::compiler and dart::compiler::target namespaces.
All code in the compiler will gradually be moved into dart::compiler namespace.
One of the motivations for this change is to be able to prevent access to
globally defined host constants like kWordSize by shadowing them in the
dart::compiler namespace.
The nested namespace dart::compiler::target hosts all information about
target runtime that compiler could access, e.g. compiler::target::kWordSize
defines word size of the target which will eventually be made different
from the host kWordSize (defined by dart::kWordSize).
The API for compiler to runtime interaction is placed into compiler_api.h.
Note that we still permit runtime to access compiler internals directly -
this is not going to be decoupled as part of this work.
