Gotta start somewhere.
All subject to revision. (Names especially.)
This gets us an end-to-end test and a starting point for client algorithm implementations.
Note that this was designed to run outside `test/`. We should be able to move it out if so desired.
Needless to say any thoughts on any of it are welcome!

While a thread is outside a safepoint it should not perform any
long blocking operation and it must not acquire a Mutex/Monitor which
can be held while being inside a safepoint.
Right now we can have this situation
GC wants to safepoint
T1 is in a safepoint, acquires lock L and wants to leave safepoint (waits for GC to finish)
T2 is not in a safepoint and tries to acquire lock L
With this CL, we ensure to always transition to a safepoint before
performing Lock/Enter/Wait.

Previously, if a function literal was used in a context where a
function returning non-null was expected, but the function literal
might return null, the migration tool inserted a cast that was
guaranteed to fail. Now it propagates non-null intent into the
function literal, so that the appropriate null checks happen inside
the function literal.

This CL extends ElementTypeProvider so that it also tracks type
parameter bounds. This allows the FixBuilder to reason correctly
about the what generic function types will look like after migration,
and that in turn prevents it from trying to add unnecessary casts.

We now track decorated type parameter bounds similarly to how we track

The actual motivator is though that test_method was failing.
I suspect that this is a linter issue, `super.toString()`, when called
from legacy library and referencing NNBD SDK, is MethodMember, and
probably linter does not handle this right. I believe that this is
not a problem we should test or fix in analysis_server, so I update
the test to verify what is implemented in the server.

Some of the tests were fairly seriously broken, so this fixes them.
Some of the tests were testing that we don't provide a fix when there is
no lint, but I don't think that it's useful to test that.
One test required no changes other than removing the marker.

Report it as a silent exception. This way it will show up in log files
and (in the future) over crash reporting (since we haven't solved the
underlying cause), but *not* to users, because it currently appears to
be harmless.
In the future we should consider a "logged-only" type of exception, once
we are confident this isn't causing secondary issues, if we don't intend
to or think we are able to solve this at a deeper level.

The Socket class will now throw a SocketException if the socket has been

The NNBD migration required making subtle changes to some dart:io
semantics in order to provide a better API. This change backports one of
these semantic changes to the unmigrated SDK so any issues can be
discovered now instead of blocking the future SDK unfork.

99th percentile execution time is at 20s, so with twice as many results

Introduces NativeRepresentation and NativeLocation for the compilation of FFI.
NativeRepresentations are able to express all representations (or types) of the native ABIs we bind to with FFI, this is more representations that than that are used in Dart itself.
NativeLocations are able to express all locations of the native ABIs we bind to with FFI, this is more types of locations than that are used for the Dart calling convention.
See the documentation in the respective files.
These NativeLocations and NativeRepresentations are computed by the NativeCallingConvention and consumed by the Marshaller and Assemblers.
This reenginering is required for go/dart-ffi-by-value, hardfp (Arm S and D fpu registers), and iOS 64 bit (non-word-aligned stack arguments).
In addition, by using the NativeRepresentations we also get slightly reduced code size:
* The tracking of sizes is improved, so less sign/zero-extension operations are required.
* UnboxedWidthExtenderInstr is fully removed, the size extension is done inside the native moves, coalescing moves and size extension when possible.
* BitCastInstr is only used when really needed. This reduces code-size on arm32 softfp.
This fixes the iOS arm64 calling convention, manually tested with https://github.com/flutter/flutter/pull/46078 and https://dart-review.googlesource.com/c/sdk/+/131074.
