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.
Original change's description:
> [vm] Replace array GetIndexed graph intrinsics with flow graph builder implementation
>
> _Array, _GrowableList, internal and external typed data 'operator []'
> are now implemented in the flow graph builder.
>
> Unlike graph intrinsics, flow graph created in the flow graph builder
> can be used by the inliner. Corresponding graph intrinsics and native
> methods are removed.
>
> Also, this change adds missing external typed data indexing operations.
