This improves the exhaustiveness handling for null assert patterns
by extending the space of the subpattern with the null space. This
reflects the fact that null assert will throw on `null` and can
therefore be considered to cover that case.

`hashCode` requires that equal objects have the same hash code.
However it doesn't (and cannot) require that inequal objects have
different hash codes. Remove the invalid check.
This makes the test pass on dart2wasm, which currently implements
closure hash code as:
// Simple hash code for now, we can optimize later
@override
int get hashCode => runtimeType.hashCode;
Note: this change alone does not make the whole file pass with
dart2wasm, there's another (unrelated) issue which will be fixed
separately.

- Only add type as input if the info doesn't have one. This was causing nulls to be added into implementations of `==` where they weren't being added before.
- Add a mechanism to avoid virtual targets for dynamic calls with specified selectors. Inference results suffer when virtual targets are used for the 3 specified selectors as these lead to intercepted calls that cannot be optimized out.
After this change in a big program there are 42 member type differences between the linearized and current algorithms in a program with ~84.5k member types. Some of those 42 are actually improvements on the current algorithm that we get since the new algorithm no longer imposes a refinement limit (except to catch non-converging types).

We still need -fPIC in some places because we build a few shared libraries for FFI, so copy some of Fuchsia's GN setup to use -fPIE or -fPIC as appropriate.
Account for older gcc that does not default to -fpie.

That forces them to be nullable, unless there is a
reason to be non-nullable.
I excluded setters and generic arguments from this
nullification. Also we don't touch `operator ==`, where
changing argument type to `Object?` doesn't make sense.
This is a response to some teams asking for the migration
tool to be super conservative. Otherwise people migrate
some methods to have non-nullable arguments and they are
still called with `null`s at runtime in mixed mode.
That was the only way I found to implement the "nullable
arguments by default" request.
It broke a good deal of tests. I updated them mostly to use
private functions, so the old behavior is preserved, but
sometimes I couldn't figure out a way to trigger the desired
codepath with the new behavior... I also suspect that now
there is a non-zero amount of tests that are passing but
don't really exercise what they were supposed to exercise.
