connect to DDS without relying on a redirect.
Some WebSocket implementations (particularly dart:html's) don't follow
redirects and don't provide the user with the message returned by the
server.
This CL adds 'getWebSocketTarget' as an RPC which returns the
URI that should be used by the client to connect directly to the proper
web socket target. In addition, the "implicit-redirect" forwarding has
been removed.

Normally the heap grows in steps proportional to the size of the heap, so it grows faster the closer it gets to memory exhaustion.
The closer the heap size approaches --old_gen_heap_size, the less the heap will grow between GCs. This is useful on systems that respond to low memory conditions by killing processes instead of failing allocations. It is expected the asymptote will be chosen as some fraction of memory available from the OS (hundreds of MB on mobile).

Previously the help messages for 'dart run' were output by a secondary
VM spawned solely to print the VM's help message. However, this help
message was not consistent with those found for other DartDev commands.
With this change, the 'run' command:
- Uses package:args to create a help message consistent with other
DartDev commands.
- No longer accepts arbitrary options and is instead restricted to a
subset of common flags. Passing a VM flag which is not included in
this subset of commands will result in an argument error if passed
*after* the 'run' command. Other VM flags can be passed immediately
following 'dart' and before the DartDev command.
- No longer outputs the VM verbose options when invoked with '--help
--verbose'. VM verbose options and the original VM help message can
be viewed by running 'dart --help --verbose'. This makes uncommon
VM flags used for development less visible to regular users.
- Now properly forwards the subset of VM options accepted by 'run' to
the VM (e.g., 'dart run --observe --no-pause-isolates-on-exit foo.dart'
would have ignored '--no-pause-isolates-on-exit').

"\\?\" prefixed path is not properly supported. Arguments historically
were parsed as a Uri, which converted backward slashes into slashes. It
used to work because Win API is able to handle slashes as separators.
But "\\?\" has a special meaning and should not be changed. '?' is also
invalid char in the URI. So it leads to a crash.
The best solution is to avoid using URI to parse the path. This cl is a
workaround for crashing.

Moves AllocateObject and CreateArray instructions down to their
dominant use (use that dominates all other uses) when such a use exists
and the move is not hampered by environment uses (which can happen when
the allocation is inside a try block).
This improves write barrier elimination for inlined constructors, since
it moves the allocation after evaluation of the arguments. Any Dart
calls in an argument would disable elimination after it.
The optimization is particularly effective for Flutter Widget code,
since such code typically contains many nested constructor calls.
Reduces instructions size of Flutter Gallery by about 0.8%.

Before this, we had to use PRECOMP_NO_CHECK() for any entries that
involved field offsets that came after NOT_IN_PRECOMPILED() fields,
because the offsets would differ between JIT and AOT. That removed
the check in dart.cc that the offsets match, but that just meant
that precompiled code that used these offsets were wrong.
One possible workaround is to just lift any field definitions whose
offset might be used in precompiled code before any NOT_IN_PRECOMPILED()
defined fields, but this means otherwise unnecessary changes in the
Layout classes.
Instead, just fix the runtime offset generation/retrieval by splitting
the list of offsets into two parts: offsets common to all modes and
offsets only valid in JIT mode. While this complicates the code that
generates and imports these offsets, it ensures that our code generation
actually uses the right offsets for the target mode.
In addition, by doing this split we can add checks for uses of JIT-only
offsets when in precompiled mode. Adding these checks found some uses of
JIT-only field offsets in code compiled in precompiled mode. (These
uses may have been benign if the stubs that included the uses were never
called in the precompiled runtime, but now there's explicitly a check
for precompiled mode around these uses.)
Also remove the unused ARRAY_STRUCTFIELD type from offset lists.

Before, DRT_InterpretedInstanceCallMissHandler expected either
Resolver::ResolveDynamic or InlineCacheMissHelper to return a non-null
function. However, this only happens when lazy dispatchers are enabled.
Now, DRT_InterpretedInstanceCallMissHandler is allowed to return a
null function if lazy dispatchers are disabled, and
Interpreter::InstanceCall checks the result for null. If null, then
lazy dispatchers must be disabled, so Interpreter::InstanceCall
delegates handling the miss to DRT_InvokeNoSuchMethod, which has been
updated to do the same resolution algorithm as
DRT_NoSuchMethodFromCallStub.

Also relands the followup CLs:
"Perform non-covariant checks when dynamically invoking callables."
"Use AreValidArguments so that names are checked as well."
Original description of first CL:
This change only affects compilation when running in non-precompiled
mode with --no-lazy-dispatchers enabled.
Instead of always compiling in non-covariant checks, even for closures
not called dynamically, remove the non-covariant checks from the closure
and instead do the non-covariant checks for dynamic calls during the
NoSuchMethodForCallStub fallback by calling
Function::DoArgumentTypesMatch.
Adds two overloads for Function::DoArgumentTypesMatch, one which takes a
function type argument vector and one which takes neither an
instantiator type argument vector or a function type argument vector.
For the versions that are not explicitly passed a type argument vector,
an appropriate one is constructed using the arguments. If there is not
enough information in the arguments, then we fall back to assuming the
empty type argument vector for the instantiator case and instantiating
to bounds in the function type argument case.
Fixes Function::DoArgumentTypesMatch to handle generic functions and to
check arguments appropriately according to the active null safety mode.
For generic functions, the provided or resulting function type vector
has non-covariant checks performed against the type parameter bounds.
This change uncovered one test that was incorrectly passing in strong
mode, see https://github.com/dart-lang/sdk/issues/42688 for details.
Original description of second CL:
The VM only does this when the callable function does not expect dynamic
invocations. Otherwise, performing the checks would be redundant, as the
function body already contains the appropriate non-covariant checks.
Third CL had no additional description.
