This moves Http code into dart:_http. dart:io then imports and
re-exports dart:_http. This is the first stage of moving
dart:_http into its own pub package.

This enables running benchmarks (e.g., DeltaBlue) on d8. d8 tip (with
es6 modules) appears quite a bit faster than the latest dev nodejs (with common modules).

Two different optimizations conflicted (in the SDK, == methods must take care to consider a null value, but at the same time tearoff == was optimized), so it fixes that. Also adds a test for this.

This should improve performance of these members in most cases:
- toString
- operator ==
- hashCode
- runtimeType
- noSuchMethod
The helpers for checking `null` and then dispatching to the method are now very small again. Also, because we can lookup symbolized names always, we can start taking advantage of this in our Map/Set implementations (for a follow up CL).
This also improves correctness of these helpers given JavaScript objects; we were previously falling back to calling a Dart method name like `.hashCode`, which is incorrect (except for `toString` where fallback is probably the correct behavior).

This has a few related fixes:
fix#30461, DDC now generates covariant checks for superclasses with the correct substitution.
fix#29483, Analyzer can resolve the function type literal syntax correctly when used in type bounds and type arguments.
fix#30095, replace use of DDC's StrongModeError private type with TypeError.
It also has some refactoring to simplify how DDC emits the initialization code at the start of function/method bodies. We no longer jump through AST parent pointers.

Fuchsia requires the ability to sandbox Isolates w.r.t. file IO.
When a new Isolate starts, Fuchsia will pass the Isolate an object
called a namespace. We can translate the namespace object into a
file descriptor suitable for passing to the *at() family of
POSIX file system calls. The file system calls will then
have visibility only into the specified namespace.
We also plumb Namespaces through on all the other platforms as well to
make the change easier to test and so that in the future we can
implement e.g. per-isolate cwds.
This change adds a new internal class to dart:io called _Namespace,
which is implemented in a patch file. See:
sdk/lib/io/namespace_impl.dart
runtime/bin/namespace_patch.dart
The embedder can set up a non-default namespace by calling
_Namespace._setupNamespace during Isolate setup.
Instances of _Namespace have a native field that holds a pointer
to a native Namespace object. See:
runtime/bin/namespace.h
Calls from e.g. file_impl.dart are now also passed a
_Namespace object. The implementations in e.g. file.cc and
file_linux.cc then extract the namespace, and use it to compute a
file descriptor and path suitable for passing to e.g. openat().

fixes#30495 - optimize subtype cache
fixes#30464 - optimize `is List`
Additional changes:
- optimize double type checks
- optimize Object type checks
- optimize FutureOr<T> checks
- optimize interface checks for some dart:core and dart:async types (List, Map, Iterable, Future, Stream, and StreamSubscription )
- optimize checks for generic class default instantiations and exact instantiation (e.g. `C<dynamic>` on any instance `C<T>`, and `C<T> on an instance of C<T>`
- optimize checks for native types
- optimize getReifiedType
- optimize dcall/dsend/dput checks to use faster Type._check pattern
- optimize instanceOf/cast functions by moving special cases to appropriate types
- optimize Object.runtimeType
- optimize JS interop type checks
- optimize all function type checks
There's more we can do (especially for class/interface types) but this should cover a lot of cases.

Eliminate numerous type checks not needed in strong mode. Use
private nullability annotations instead of inline JS to mark known
non-null variables, and to make the compiler generate null checks
for null checked variables. Use nullability annotations and code refactoring to
remove redundant null checks and to move checks out of loops.

Previously, the string set up by the embedder was eagerly passed to
Uri.parse during Isolate startup. This is expensive both in time and
memory footprint. This CL causes Uri.parse() to be called only
when needed. This change will allow reducing the memory footprint
of Fuchsia's Dart content handler on hello world by ~1MB.
