In the VM, factory constructors always had an extra "type arguments"
parameter, even if class is not generic. Factory constructor bodies
were using class type parameters instead of function type parameters.
This results in extra code when calling non-generic factories
which is slightly inefficient in terms of code size and performance.
Also, it creates an additional complexity throughout the system as
factories should be special cased in many places.
This change removes artificial "type arguments" parameter, treating
factory constructors basically as static methods. This matches
kernel AST representation.

This is a reland of commit d24b5d1f5e
On top of the original change, the following is fixed and improved:
1) Flow graph builder (FGB) body is now also applied to
dynamic invocation forwarders (similarly to graph
intrinsics).
2) Frame can be omitted for functions which have a
call on a shared slow path. This is needed to make
FGB implementation of GetIndexed frameless, as it has
GenericCheckBound which calls on shared slow path.
(Graph intrinsics are frameless).
3) Range analysis is enabled for force-optimized functions,
so more efficient code can be generated for boxing
instructions. Range analysis is fixed to avoid crashes
and correctly intersect ranges with constant boundaries
(needed for some force-optimized FFI functions).
4) EliminateStackOverflowChecks pass is enabled for
force-optimized functions so CheckStackOverflow can be
eliminated.

This reverts commit d24b5d1f5e.
Reason for revert: performance regression
(Graph intrinsics are applied to dynamic invocation forwarders,
but flow graph builder implementation isn't.)

Currently we have things called XPtr which are not what you get from ptr().
Old world:
handle->raw() returns RawObject* (tagged)
raw_obj->ptr() returns RawObject* (untagged)
After 6fe15f6df9:
handle->raw() returns ObjectPtr
obj_ptr->ptr() returns ObjectLayout*
New world:
handle->ptr() returns ObjectPtr
obj_ptr->untag() returns UntaggedObject*

GrowableArrayMarker was a class that implemented int and was used to
enable implementation of default List factory constructor in pure Dart:
factory List([int length = GROWABLE_ARRAY_MARKER]) {
return identical(length, GROWABLE_ARRAY_MARKER) ? new _GrowableList<E>(0)
: new _List<E>(length);
}
Its existence complicated all kinds of things in the VM and it is finally
time to remove it.
Instead we build List factory body directly in IL.
This CL also provides inlining rule for `new List(n)` case.

avoid overflow.
For each variable size heap object, compute the maximum number of
elements and use that in the ::New functions to avoid overflow. If a
bad length/size reaches a ::New function, that is a FATAL error -- the
problem should have been caught earlier by the dart api or by the
library code.
Add "border guards" in the dart api and in library calls which cause
new variable size heap objects to be allocated. We check for invalid
length/size and throw explanatory error messages.

The purpose of this change is twofold:
1. Source in the bin directory can now use the same assertions as
source in the vm directory. The ASSERT macro used by the code
in runtime/bin was just defined to use assert from the standard
C library.
2. Moving other implementation parts from runtime/vm to
runtime/platform (e.g. classes Monitor and Mutex) for sharing
between runtime/bin and runtime/vm will be easier as these
implementations rely on these assertion macros.
Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.
All the code for asserts is still in the dart namespace.
Also re-arranged the order of includes to be alphabetically in
the files touched.
