Dynamic invocations of generic functions might not pass type arguments.
The type arguments need to be filled in with the default type arguments
calculated by the CFE.

The behavioral difference is that named and optional arguments are filled in
with their default values in the `Invocation` object passed to `noSuchMethod`.
On the implementation side we make NSM forwarders concrete and fill in their
bodies in the CFE. The custom (and somewhat hacky) VM support is no longer
needed, and Dart2JS can benefit from this implementation as well.
According to discussion on #33031 we will be able to re-land this soon without
breaking Mockito.
Prior failures on precompiler bots are fixed in Patchset 2.

sync*/async/async* generators have two parts: an entry, which does
checks and computes the element type of the result, and a body, which
is transformed after lowering to JavaScript.
The split ensures that the code for checks is done at function call
time, rather than e.g. in the moveNext method of a sync* iterator.
A following CL with optimize the split to generate one function when
there are no checks and the type argument is simple enough for textual
substitution.

This reverts commit cf78da8a48.
Reason for revert: introduces significant performance regression (~30%) on analyzer benchmarks (warm-analysis) without clearly visible hot-spot.
Original change's description:
> [VM] Reduce Smi size to 32 bit on 64 bit platforms
>
> This reduces small tagged integers on 64 bit platforms from 63 bits to
> 31 bits plus one tag bit.
> This is a step on the way to compile-time-optional compressed pointers
> on 64 bit platforms. See more about this at go/dartvmlearnings
> This causes a slowdown for some uses of integers that don't fit in 31
> signed bits, but because both x64 and ARM64 have unboxed 64 bit
> integers now the performance hit should not be too bad.
>
> This is a reapplication of

Type arguments that require a subsitution need the interceptor to
access the substitution function.
- Add an interceptor input to HTypeInfoReadVariable
- Add an entry point getRuntimeTypeArgumentIntercepted that takes the interceptor.
- Optimize uses that do not need the interceptor.
The interceptor is cheap to get from the context in the common case
that the type variable access is directly in an instance method.
A typical use (broken)
var t1 = H.getRuntimeTypeArgument(receiver, "ListMixin", 0);
becomes
var t1 = H.getRuntimeTypeArgumentIntercepted(this, receiver, "ListMixin", 0);

The whereType method silently does the wrong thing without methods,
so make it throw until we turn them on everywhere.
