224ca74ae4 [asm.js] Propagate language mode to exported functions.
This makes sure the language mode of the module is correctly propagated
through the WebAssembly module, so that exported functions are allocated
with the correct language mode. It extends the existing {ModuleOrigin}
enum to consist of three values now.

cd34523b9b [wasm][tests] Add proposal tests to the wasm spec tests
With this CL we add proposal tests to the wasm-spec-tests. For this I
extended the update-wasm-spec-tests.sh script. Additionally to
generating the spec tests it does the following:

For each proposal it identifies those tests that are different to the
spec tests, and then copies those tests also to the wasm-spec-tests
directory.

Additionally I adjusted the test runner of the wasm spec test to
run the proposal tests with the correct flags.

d270056f25 [perf] mask timeout failures if they succeed after retries
perfrunner returns a failure if the build timeouts at any point even if it's
successful after retries. It tries to surface up the timeout issue. Due to this,
some bots stay red consistently, and confuses the sheriffs.

This CL masks the timeouts if the suite succeeds in the end.

14274bb16a [torque] Use @generateCppClass in some simple cases
This change is mostly mechanical, but it's worth mentioning a few
slightly interesting cases:
- A couple of field definitions didn't match the signedness of their
  corresponding accessors.
- The generated accessors for Smi data use Smi values directly, but
  usually we want C++ accessors to use ints instead. I added a macro
  that hides the generated Smi accessors and exposes int accessors,
  but we might consider generating int accessors directly.
- The data held in some fields is described in comments next to the
  accessor definition for those fields. With automatically generated
  accessors, those comments need a new home. In this change I put them
  in the Torque object definition, but I'm open to other suggestions.
- gen-postmortem-metadata couldn't find updated class definitions after
  they got split across multiple lines, so I changed its matching
  logic. (Ideally debug-support.cc should be a Torque compiler output
  rather than something that involves parsing C++ with regexes, but
  this makes it correctly report subclass relationships for now.)
- The end offsets generated by Torque were off by one from the values
  that would be generated by DEFINE_FIELD_OFFSET_CONSTANTS.

b086cb7b9a Check that function was prepared before optimizing using manually
With lazy feedback allocation and bytecode flushing we need to call
%PrepareFunctionForOptimize before we call %OptimizeFunctionOnNextCall/
%OptimizeOsr. This cl:
1. Adds an additional state in pending optimized table to check if the
optimization was triggered manually.
2. Changes the compilation pipeline to delete the entry from pending
optimized table only if the optimization was triggered through
%OptimizeFunctionOnNextCall / %OptimizeOsr.
3. Adds a check to enforce %PrepareFunctionForOptimize was called.
4. Adds a new run-time flag to only check in the d8 test runner. We
don't want this check enabled in other cases like clusterfuzz that doesn't
ensure %PrepareFunctionForOptimize is called.

fa2bed3f74 [regexp] Move the RegExpSpeciesProtector to the native context
Prior to this CL, it was possible to pollute another context's
fast/slow-path state for RegExp builtins due to the species protector
being per-isolate rather than per-context. Among other things, this
means that iframes can slow down the main site, and slowdowns persist
across page reloads and navigation within the same tab.

This CL thus moves the RegExpSpeciesProtector to the native context.

The same should be done for all other protectors in the future.

2fe2a08b0c [wasm] Introduce WasmIndirectFunctionTable
This is the first of three CLs which refactors indirect function calls
through tables with index > 0 to work without runtime calls.

The first CL introduces the WasmIndirectFunctionTable heap object. For
a table of type anyfunc within a WebAssembly instance,
WasmIndirectFunctionTable stores the size, the signature id's, the
call targets, and the reference parameters for that table. I used the
names that are already used for the matching fields of the
WasmInstanceObject.

The second CL expands the IndirectFunctionTableEntry to work also on
WasmIndirectFunctionTable objects. All changes to a function table go
through this class.

The third CL introduces uses of the WasmIndirectFunctionTable. In this
CL I change the code generation in TurboFan to replace runime calls with
direct accesses to the new WasmIndirectFunctionTable. Additionally I
extended the initialization of WasmIndirectFunctionTable, and also
implement Table.grow.

dfcc46a6c7 [DevTools] Roll inspector_protocol (v8).
New Revision: 8b7ea912e516a6daa61487c700687a9426e3a396

Update v8 files / build config accordingly.
- There's now a new library in third_party/inspector_protocol,
  bindings/bindings.h, which is configured much like encoding/encoding.h.
  It doesn't have much stuff in it yet, but will soon get more code
  that would otherwise need to go into jinja templates.
  It also comes with a new test, only a smoke test thus far.

92147e3aca [modules] Introduce SyntheticModule
This change is a partial implementation of Synthetic Module Record as specified here:
https://heycam.github.io/webidl/#synthetic-module-records

This includes:
- Introduce SyntheticModule class inheriting from Module.
- Extend v8::Module interface in v8.h to include Synthetic Module APIs, with corresponding
  implementations in api.cc.
- Provide SyntheticModule implementations of PrepareInstantiate, FinishInstantiate, and SetExport.
- Provide cctest unit tests for the implementations in the preceding item.

We will follow up with further submissions to implement the remaining members of
SyntheticModule (ResolveExport and Evaluate).

12b45fdf00 [gdb] Add gdb macro 'pn' that prints TurboFan nodes
The macro pn ensures that TurboFan nodes can be easily
printed in gdb, even in release builds where Node::Print
is sometimes not available (because all uses have been
inlined).

This CL also modifies the print function to deal gracefully
with nullptr input nodes, which is helpful for debugging.

1ca89b8c71 [foozzie] Enable passing extra flags on command line
Currently, probabilities for extra flags are calculated in the correctness
fuzzer harness, which makes the RNG fragile when bisecting backwards, when
the script's config changes during bisection.

This adds the possibility to pass extra flags on command line to the
script. After a grace period, we will migrate the flag calculation to
clusterfuzz.

".mjs" extension can be used for ECMAScript modules in addition to the standard
extension ".js" we use for the base tests.

This CL generalizes the {TestLoader} to accept multiple extensions for

18fcd0b4ee [clusterfuzz] Teach clusterfuzz to use --no-lazy-feedback-allocation
To correctly fuzz the behaviour of optimized code and ICs we need to
allocate feedback vectors. So for the configurations testing these we
should turn off lazy feedback allocation.

It is also good to fuzz without lazy feedback allocation on other
configurations to flush out any other issues. So we also fuzz this with
0.35 chance. We also fuzz aggressive lazy feedback allocation (allocate
feedback vectors on first branch / return) with 0.05 chance to test
corner cases related to lazy feedback allocation.

76c1e829e3 [torque] Support 'real' internal classes
Rework the implementation of non-external Torque classes to use
Struct machinery rather than FixedArray machinery. This allows
Torque-only defined 'internal' classes to the automatically generate
class verifiers and printers.

As part of this change, generate C++ boilerplate accessors for
internal Torque classes, since this is a pre-requisite for the
verifiers, printers and other Struct-based functionality.

Moreover, augment the header-generating functionality in Torque
to create separate header files for field offset definitions,
internal class C++ definitions and instance types.

4965a34e0f Added !mem and !where extensions to windbg.js
The extensions require isolate address to be set but don't rely on calling
any runtime functions, which makes them viable for post-mortem debugging,
if the corresponding memory is included into the dump

!set_iso(isolate_address)
    call this function before using !mem or other heap routines

!mem or !mem(\"space1[ space2 ...]\")
    prints memory chunks from the 'space' owned by the heap in the
    isolate set by !set_iso; valid values for 'space' are:
    new, old, map, code, lo [large], nlo [newlarge], ro [readonly]
    if no 'space' specified prints memory chunks for all spaces,
    e.g. !mem(\"code\"), !mem(\"ro new old\")

!where(address)
    prints name of the space and address of the MemoryChunk the
    'address' is from, e.g. !where(0x235cb869f9)


Output from !mem would look something like this:

0:000> !mem("old")
Heap at 0x210652b8838
Im   address:	 object area start - end (size)
OldSpace (allocating at: 0x1703dae7a20):
*    0x33d9a8c0000:	 0x33d9a8c0138 - 0x33d9a8f1000 (0x31000)

2. Fields that might not exist
3. Fields that are waiting for MaybeObject support in Torque

This also fixes running tools/run_perf.py --help and adds logging for the
