This change includes the following:
* Decision to use subtype range checks is revised to work regardless of
the NNBD mode.
* Handling of dynamic/Object/void is removed from SlowTypeTest stub
as we use TopTypeTypeTest stub for the top types. That handling was
unnecessary but harmless. However, in NNBD strong mode it becomes
incorrect for non-nullable Object.
* TypeTestingStubGenerator::OptimizedCodeForType now falls back to
TypeTestingStubGenerator::DefaultCodeForType instead of directly
using StubCode::DefaultTypeTest(). This refactoring is needed to
avoid duplicating a more complicated logic in
TypeTestingStubGenerator::DefaultCodeForType in the future.

This prevents them from being called dynamically.
Moreover, it prevents asFunction from being called on a non-NativeFunction type argument, simplifying the amount of manual checks.
Note that this CL had to change the CFE and analzyer, and their tests (including mock_sdk) as well.
This can potentially be a breaking change, as the extension methods are only visible when `dart:ffi` is imported, while methods on objects are always visible.

NullCheck pc descriptors are added to all dispatch table calls where the
receiver may be null (and the selector is not one implemented by null).
All null entries in the table go to the NullError runtime entry, which
reads the NullCheck pc descriptor to get the name of the called member
for the error message.

The instruction sequences for dispatch table calls have three versions,
depending on the selector offset relative to where the dispatch table
register is pointing:
- Optimal: Zero offset
- Small: A small range of positive and negative offsets
- Large: Larger positive offsets
The exact limits for small offsets depend on the target architecture.
This commit changes the dispatch table layout algorithm to favor
offsets corresponding to smaller instruction sequences for selectors
with many callsites.
As a result, == (which is by far the most abundantly called selector)
gets the zero offset, and most commonly used selectors (such as [],
iterator, current and moveNext) usually get small offsets on ARM and
ARM64 targets (where the range of small offsets is reasonably large).

For each selector, count the number of calls to the selector that are
both reachable and polymorphic according to the TFA. Only include
selectors in the table with non-zero counts.
This reduces the dispatch table size by 30% in dart2js and by 49% in
Flutter Gallery (312k memory use reduction on ARM64).
Call counts are transferred in a dedicated metadata block with
per-selector information. This mechanism also prepares for transferring
other per-selector information in the future.

Some visitor methods were missing in the TFA transformation, causing
some call sites (such as PropertySet) to not be instrumented with
metadata communicating the analysis results.
Visiting all instance call sites (including PropertySet) is also needed
by table dispatch to collect correct summary information on selectors.
