V8_libbase.dll, in a component build where the dll is created,
statically links against shlwapi.dll. Shlwapi is only needed for a
single use within the debug stacktrace code and is therefore not needed
in most cases. Statically loading shlwapi also brings in user32.dll and
gdi32.dll, so this is a decent perf hit which is generally unnecessary.
This changes delayloads shlwapi so that is only loaded when actually
used.

FixedArray object in LO space are processed incrementally in ranges of slots
size kProgressBarScanningChunk to reduce latency when returning to the
processing loop is critical. A progress bar stores how much slots have been
processed already.
In the case of regular concurrent marking there was a guarantee that the
object was only processed by one thread (main *or* concurrent marking
thread) at the same time.
However, some optimizations that avoid write barriers for each
individual write operation emit a batched write barrier that requires
re-visiting the FixedArray for the marking barrier. In such cases, the
progress bar would be reset using relaxed stores which is problematic as
the concurrent marking thread could race on setting its own progress on the
progress bar. As a result, the array would only be re-scanned partially.
The fix involves using CAS to set the progress bar and bail out in the
case an inconsistent state was observed.
In the following:
MT... main thread
CM... concurrent marking thread
The interesting cases are:
1. MT *or* CM processes the array without interfering: Progress bar is
updated monotonically without failing.
3. MT interferes with itself: The progress bar is just reset and the main
thread will restart scanning from index 0. The object is added twice to
the marking worklist and processed each time one of the entries is
retrieved from the worklist.
4. MT interferes with CM:
4.a.: CM processes a range of slots and re-adds the left overs by
setting the progress bar and re-adding the array to the worklist. In
this case CM *and* MT process the array from index 0. The first time
the CAS for setting the progress bar fails on either of the threads,
the looser will bail out and leave processing for the winner.
4.b.: CM is interrupted while processing a range of the array and
fails in setting the progress bar for the left overs. In this case
the CM bails out right away and the main thread starts processing
from index 0.
In addition, there is a transition from index 0 to the index of the
first actual slot. This transition makes it possible to observe a reset
while processing the first actual chunk of slots.

The `compiler-trace-flags.js` test just makes sure the various --trace-turbo*
flags do not cause V8 to crash. However, on builds with no snapshot, they would
generate a *lot* of output as they were tracing the compiler while generating
the snapshot.
Let's set the `--trace-turbo-filter` flag to make sure we only trace the test
functions. Sadly, WASM functions do not have a name, just an index, so we have
to split this test into two.

Original message:
With this CL it is possible to use any anyfunc table in call-indirect,
not just the first table.
The current implementation is based on runtime calls. This is just an
initial implementation which should be replaced by a
dispatch-table-based eventually. However, this implementation allows
us to move forward with the anyref proposal implementation.

When running wasm tests, the interpreter previously used a static
collection of function indexes stored in WasmTable to perform
call_indirect calls internal to that module. This has the wrong behavior
if the table is changed (via WasmTableObject::Set, `table.copy`, or
`table.init`).
This CL changes the cctests to always generate an intepreter entry for
all functions, and stores those entries in the dispatch table. This
allows us to use the same execution path as for non-testing code.
The interpreter entry compiler needed to be changed to support
multi-value returns too, since a 64-bit integer return value may be
lowered to two 32-bit integer returns.

This prepares a refactoring to add and publish compilation results in
batches. For this, we need to separate the two phases, so that we can
lock the module, allocate all the code space, release the lock, copy
the code, lock the module, publish the code, and release the lock
again.
In particular, this CL does the following:
1) It removes the {AddOwnedCode} method. The functionality of creating
the {WasmCode} and memcpy'ing the instruction into that is done in
the other {Add*Code} methods. Adding to {owned_code_} is done in
{PublishCode}.
2) {PublishInterpreterEntry} is now functionally equivalent to
{PublishCode}, so it's removed.
3) After {AddCode}, the caller has to call {PublishCode}. In a
follow-up CL, this will be called in batches (first {AddCode} them
all, then {PublishCode} them all).
4) {AddCompiledCode} now assumes that the {WasmCompilationResult}
succeeded. Otherwise, the caller should directly call {SetError} on
the {CompilationState}.
5) {PublishCode} is now the chokepoint for installing code to the code
table, the owned code vector, the jump table, and setting interpreter
redirections. It replaces previous direct calls to {InstallCode} or
explicitly adding to {owned_code_}.
6) Increasing the {generated_code_size_} counter is now done in
{AllocateForCode}, which is the chokepoint for allocating space for
generated code. This way, we will only increase this counter once
once we allocate in batches.

This removes the special casing for the lazy compilation stub which used
to have its own code kind, just so that the stack walker would properly
recognize its frame.
Also, by re-using the existing machinery for runtime stubs we no longer
need to copy this stub into the native module and get all the niceties
that come with embedded builtins for free.
Thirdly this will make it easier to start lazy compilation from the
background or to do it on a per-function basis without requiring yet
more special machinery, since {NativeModule::SetLazyBuiltin} no longer
requires access to the Isolate.
Kudos for the inspiration for this cleanup go to Frederik, I merely did
some of the legwork.

'third_party/android_tools/sdk' is being replaced with 'third_party/android_sdk/public'.
This CL updates our DEPS pointing to the old path.
Note: 'android_tools' dependency is duplicated with the new path since there are users of the old and new at the same time.

Previously, the builtin BigIntToWasmI64 and its calling descriptor had
an inconsistent name, not reflecting the signature which is i64 to BigInt.
This CL removes BigIntToWasmI64 in favor of I64ToBigInt. Also for
consistency the Wasm tranpoline has been renamed from BigIntToWasmI64
to WasmI64ToBigInt.

With this CL it is possible to use any anyfunc table in call-indirect,
not just the first table.
The current implementation is based on runtime calls. This is just an

The array allocated in {SetInterpreterRedirection} was accidentally
left uninitialized, which could result in later calls to
{has_interpreter_redirection} to return true. In that case, we would
not patch the jump table when publishing the code, and would then crash
during execution.
This was uncovered by an unrelated change. It's covered by existing
tests though, we were just lucky so far that the relevant bits were 0
for some reason.

This is just one small unit test for now. As we expect to adapt the
encoding this is more of an exercise than exhaustive testing.

SaveFlags previously worked by re-setting the flags using the command
line. Unfortunately, this could reset flags being used by concurrent
processes, which would cause TSAN issues.
Now, SaveFlags stores a copy of the state of all flags on creation, and
only resets changed flags in its destructor. It does this by (ab)using
the flag-definitions.h pseudo-header, adding a new mode to that header
which applies an includer-defined macro to each flag definition.
