The tutorial doc was mistakenly _not_ in the doc/ directory.
The icons show up as way too big, so I use inline HTML to specify
their width, so that they look good inline.
I add light mode icons, and use GitHub (and dartdoc)'s support for
switching between light mode and dark mode images.

When the heap limit is reached, directly unreachable objects are reclaimed but objects that will be unreachable after a finalization are not, and there needs to be enough headroom between opportunities for finalizers to run (returning to the event loop).
So only do the finalization thing with the upper, high-mutation part of the splay tree and remove it from the lower, write-once part. The high-mutation part is what's more interesting for GC stress testing.

Expressions can also occur in patterns, either after an equality or
relational operator (e.g. `== e`), or after `const` (though what's
allowed after `const` is heavily restricted). We need to make sure
that the expression parser doesn't greedily treat `=>` as introducing
a function expression when parsing these constructs inside a switch
expression.
But it's ok to allow function expressions inside list patterns, map
patterns, parenthesized patterns, and in the argument part of object
patterns. (These will be rejected by a later stage of analysis
because expressions inside of patterns must be const, and a function
expression can't be const. But the parser should still accept them so
that we can give useful error messages).
Fixes#50591.

The parser now handles maps that contain rest patterns with
subpatterns (e.g. `{'foo': _, ...var rest}`). Even though this is
invalid Dart, it still makes sense for the parser to handle it so that
we can generate higher quality error messages.
The shared type analyzer now generates an error,
`restPatternWithSubPatternInMap`, if it encounters this error
condition.

The rules are:
1. Arguments annotated with `@Optional` must be nullable (that part
worked before this change).
2. Arguments annotated with `@Attribute` must be nullable if it's
a constructor of a component (`@Attribute` can also appear on
arguments of directives constructors, it doesn't provide any signal
in the latter case).
3. Arguments of constructors of components or `@Injectable` classes,
that have neither `@Optional` nor `@Attribute`, must be non-nullable.

Lower the threshold for converting from a linear to a hash-based cache
on most architectures from 500 to 10.
Due to register pressure, the InstantiateTypeArguments stub on IA32
continues to go to the runtime for hash caches, and so we do not
lower the threshold for converting to a hash-based cache there.
The following are benchmark results for those benchmark that use enough
Instantiations to trigger the use of hash-based caches. In the following
tables, "Results 1" denotes the benchmark results from only this change,
whereas "Results 2" include from comparing to the results prior to
4f925105cf, when only linear caches were used.

During work on this change, an issue was found where cache lookups

These were previously only needed to support calling 'replaceWith' on
TypeAliasedConstructorInvocation, TypeAliasedFactoryInvocation and
FactoryConstructorInvocation. Instead of calling 'replaceWith' on the
nodes themselves, we call 'replaceChild' on the parent, if present.
The 'replaceChild' method on the internal node is overridden to be a
no-op. Since all these internal nodes are not supported in the
external AST and therefore must be replaced during inference, these
can only be found in subtrees that have been removed, typically in
erroneous code, and it is therefore safe to make the replacement a
no-op.

Previously, the implementation used `&` and `|` for logical-and and
logical-or patterns. That is being changed to `&&` and `||`.
As a first step, we add support for `&&` and `||`, without removing
support for `&` and `|`. In a follow-up CL I'll update existing
tests, and then after a day or two I'll remove support for `&` and
`|`. This should avoid conflicts with other patterns work that's in
