71ad48fb8f [api] Mark MarkIndependent as soon deprecated
Persistent handles are always independent these days. Users should mark
weak handles as active using MarkActive if they want to keep weak
handles that are otherwise unreachable alive across scavenges.

5aa6f58952 [cleanup] Move preparsed data into function data in SFI
Since we only ever have preparsed scope info data for functions that
haven't been parsed yet, it never overlaps with there being other
function data (such as a bytecode array). So, we can merge the two
fields.

This drops the SharedFunctionInfo size by one pointer.

f8072dbdeb [handles] Use is_convertible instead of is_base_of
std::is_base_of<A, B> has undefined behaviour if B is not a complete
type. Hence, avoid it and use is_convertible<B*, A*> instead.
This captures exactly the requirement that
  Handle<A> foo() { return produce<Handle<B>>(); }
is valid exactly if
  A* foo() { return produce<B>(); }
is valid.
Also, change some static asserts to enable_ifs in order to allow
overloading a function by different Handle types, which would cause
disambiguity otherwise.

This commit has only 32-bit implementation. After review I will add

b5997de8a9 [bigint] Fix accidental input modification in Divide
"AbsoluteDivSmall" had a shortcut path for abs(divisor) == 1 where
it would simply return the dividend as result. However, its caller
"Divide" was blissfully ignorant of this trick and would therefore
simply set the value's sign as needed, modifying the input.
This CL prevents that, while continuing to avoid the full division
algorithm for abs(divisor) == 1.

82f5cbacb0 [wasm] Turn on async compilation
We extended the platform API so that it is now possible to post
foreground tasks from background tasks. This new platform API has been
implemented now in all platforms within V8, and in the gin platform in
chrome. The implementation in node.js is still missing. I don't think
there are any node.js tests which use async compilation for
WebAssembly. Therefore we could turn on async compilation again to get
canary coverage.

d9a91da635 [inspector] Dispose the isolate in the inspector tests
At the moment the inspector tests do not dispose the isolate. This is a
problem because the disposal of the isolate is used to stop the
execution of background tasks. The missing disposal of the isolate
caused flaky tests on the bots recently. With this CL the isolates of
the inspector tests get disposed.

The disposal of the isolate requires the following changes: 1) Store the
isolate in a unique_ptr so that it gets disposed when the isolate-data
gets disposed. It is necessary to use the unique_ptr so that the isolate
gets disposed after other members of isolate-data get disposed.  2)
Dispose all sessions. The reason is that the sessions require the
isolate to exist when they get disposed because they own handles.
Sessions, however, are stored in a static map, whereas the isolate is
stored indirectly in a local variable of the main function. Since local
variables get disposed before the static map is cleared, we have to
clear the map before the end of the main function.

1cec66d31b [Liftoff] Don't force unrelated stack slots into registers
When initializing the stack state at a merge point, don't force all
stack slots into registers. Allow constants to stay constants as long
as they are not part of the merge. Otherwise we might break assumptions
of outer blocks which then try to merge a register into a constant and
fail.
Also, add some documentation to {InitMergeStackSlot} to document the
intent of the implementation.

In principle it should be possible that worker threads continue their
execution even after the platform shuts down, because the background
tasks which execute on these threads are not allowed to access the

OptimizingCompileDispatcher crash after the platform shut down. This CL
stops worker threads now when the platform shuts down to prevent any
task to execute after the shutdown of the platform.
