8a9e3f64ee [ast] Store correct source position on ThisExpression
Previously, all ThisExpression's had kNoSourcePositions leading to
incorrect error messages like this:

  ➜ d8 -e "function t() { for (const x of this) {} } t();"
  unnamed:1: TypeError: undefined is not a function
  function t() { for (const x of this) {} } t();
            ^
  TypeError: undefined is not a function
      at t (unnamed:1:11)
      at unnamed:1:43


This patch allows creation of a ThisExpression with a source position,
leading to a better error message:

  ➜ d8  -e "function t() { for (const x of this) {} } t();"
  unnamed:1: TypeError: this is not iterable
  function t() { for (const x of this) {} } t();
                                 ^
  TypeError: this is not iterable
      at t (unnamed:1:32)
      at unnamed:1:43


This patch does not remove the existing cached version of
ThisExpression and instead creates a new one when required.

d8f8a7e210 Reland "[flags] warn about contradictory flags"
This is a reland of b8f9166664
Difference to previous CL: Additional functionality to specify
incompatible flags based on GN variables and extra-flags, used
to fix the issues that came up on the waterfall.

This also changes the rules regarding repeated flags: While
explicitly repeated flags are allowed for boolean values as long
as they are identical, repeated flags or explicit flags in the
presence of an active implication are disallowed for non-boolean
flags. The latter simplifies specifying conflict rules in
variants.py. Otherwise a rule like

INCOMPATIBLE_FLAGS_PER_EXTRA_FLAG = {
  "--gc-interval=*": ["--gc-interval=*"],
}

wouldn't work because specifying the same GC interval twice
wouldn't actually count as a conflict. This was an issue with
test/mjsunit/wasm/gc-buffer.js, which specifies
--gc-interval=500 exactly like the extra flag by the stress bot.

Also, this now expands contradictory flags checking to d8 flags
for consistency.

3c422d1c5e [snapshot] Clear reconstructable data prior to d8 stress_snapshot run
The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.

With this change, mjsunit tests pass on x64.

The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.

Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.

--wasm-interpret-all also needs to be removed.

Since we don't have any non-compiling tier any more, we also remove the
implication from --jitless to --wasm-lazy-compilation. Instead, we add
another CHECK that we can't be in jitless mode if we trigger any wasm
compilation.

All tests that just ran other tests and additionally passed
--wasm-interpret-all become redundant and are deleted. Also all
regression tests that explicitly specify --wasm-interpret-all are not
needed any more.

dbbacccaa3 [weakrefs] Port FinalizationRegistry cleanup loop to Torque
To avoid shrinking the unregister token map on each pop of the cleared
cell list, the Torque implementation of the cleanup loop avoids
shrinking the map until the end of the loop.

To support that, PopClearedCellHoldings is refactored to the Torque
PopClearedCell which calls the
JSFinalization::RemoveCellFromUnregisterTokenMap and the runtime
ShrinkFinalizationRegistryUnregisterTokenMap. The former cannot GC is
and is implemented in CSA as a fast C call. The latter can GC and is a
runtime call.

This also incidentally makes uses of FinalizationRegistry without
unregister token a fast path that doesn't have to leave Torque.

1d0693e2eb [callprinter] Correctly point to the incorrect spread arg
The source position is set to the function call (console.log) not the
spread (..x), in the bytecode generator, as the spread operation is
done as part of the CallWithSpread bytecode.

The CallPrinter stops at the function call and doesn't look at the
arguments as well (in CallPrinter::VisitCall) to see if the error is
from an incorrect spread operation.


With this patch, we pass some state to the CallPrinter in the
CallWithSpread error case and check that in CallPrinter::VisitCall
before returning.

For the given source string:
```
x = undefined;
console.log(1, ...x);
```

Previously, the error was -

```
test.js:2: TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))
console.log(1, ...x);
        ^
TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))
    at test.js:2:9
```


Now, the error is -

```
_test.js:2: TypeError: x is not iterable (cannot read property undefined)
console.log(1, ...x);
                  ^
TypeError: x is not iterable (cannot read property undefined)
    at _test.js:2:9
```

Add a case for kWasmS128 in Spill. We encounter this in the
wasm-trace-memory-liftoff test, but that test was skipped on ARM and
ARM64 due to insufficient implementation of Liftoff on those archs. But
with recent changes, they are now capable of running this particular
test, so we enable it.

ba14c2f354 [wasm-simd][liftoff] Support SIMD locals
Add kWasmS128 to the list of supported types, and implement Fill for all
the architectures so that LocalGet works.

Add a new test file to contain tests that run only on Liftoff, and
assert that the code is indeed compiled by Liftoff.
We cannot rely on the nooptimization variant for testing
because by default, if Liftoff compilation fails, it will fall back to
Turbofan, and we accidentally get a test passing.

We skip these tests on mips architecture that don't support SIMD, since
there is no way to implement these, and we don't have a "lowering" phase
for Liftoff.

As we implement more of SIMD in Liftoff, we can add more
tests to this file and ensure correctness. Future patches will introduce
support for globals and params.

5c23e6b5f2 V8 Wasm locations should always be based on byte offsets
Currently there are two ways wasm locations are represented in the
inspector. This remains unchanged for now. Also, currently there are
multiple ways location is represented within V8, with the line number
sometimes being a function index and sometimes being 0, and the column
number being a byte offset which is sometimes function relative and
sometimes module relative. With this change, the line number is never
used within V8 (it is always 0), and the column number is always a
byte offset from the beginning of the module. This simplifies
translation logic and keeps it in one place, and will simplify future
changes to wasm location representation in the inspector API.

1fba044154 [destructuring] Elide coercible check for simple keys
Simple object destructuring, such as `let {a,b} = o`, is less efficient
than the equivalent assignments `let a = o.a; let b = o.b`. This is
because it does a nil check of `o` before the assignments. However, this
nil check is not strictly necessary for simple (i.e. non-computed) names,
as there will be an equivalent nil check on the first access to o in
`o.a`. For computed names the computation is unfortunately obervable.

So, we can elide the nil check when the first property (if any) of the
destructuring target is a non-computed name. This messes a bit with our
error messages, so we re-use the CallPrinter to also find destructuring
assignment based errors, and fiddle with the error message there. As
a side-effect, we also get out the object name in the AST, so we can
output a slightly nicer error message.

This assertion was borked, as it accepted obviously "same" values like

and assertNotSame to use {Object.is} underneath. It also adds a new
respective regression test (gotta test the tester).

e101b9c03c [parser] Improve error when using import decl in a script
Perform a best-effort check for module context and provide an
appropriate error.

As seen from the import-blah-script.js test, we could have invalid
import expressions in a script context that could result in an error
saying "Cannot use import statement outside a module" which isn't
the ideal error because the error is an incorrect import
expression.

But, when the developer changes to a module context, the
correct error is thrown.

To fix this, we'd have to refactor and call ParseImportDeclaration,
and then throw an appropriate error, which seems like a lot of
overhead for not enough gain.

beaf1073bd [wasm] use standard WebAssembly stack trace format
Currently, in wasm-function stack traces, v8 displays the decimal offset
from the start of the function. However, the WebAssembly WebAPI
specification says that it should be a hex offset into the module.

This change makes the stack trace display with hex module offsets, as
well as fixing all the unit tests that depended on the old behaviour.

193a261775 Reland "[stack-trace] Include API functions in Error.stack stack trace"
This is a reland of 3dd5661204

The reland introduces a new flag "--experimental-stack-trace-frames".
The flag is disabled by default, but enabled for relevant tests.
The flag stays disabled by default until API frames are eagerly
symbolized to prevent leaks in blink web tests.

Original change's description:
> [stack-trace] Include API functions in Error.stack stack trace
>
> This CL extends Error.stack to include frames of functions declared
> with the C++ FunctionTemplate API. For example, "print" in d8.
>
> Two changes are necessary:
>   - HandleApiCall and friends need to go through an BUILTIN_EXIT frame
>     instead of an EXIT frame. The existing stack-trace machinery will
>     then pick up FunctionTemplate frames without additional changes.
>   - Turbofan doesn't go through HandleApiCall, but instead uses an
>     ASM builtin to enter FunctionTemplate functions. A "marker"
>     frame state is needed to include these frames in the stack trace.

5cc9f9bc5f Revert "[stack-trace] Include API functions in Error.stack stack trace"
This reverts commit 3dd5661204.

Reason for revert: causes leak tests in blink layout tests to fail: https://ci.chromium.org/p/chromium/builders/ci/WebKit%20Linux%20Trusty%20Leak/34295

Steps to reproduce:
- Build blink_tests with following GN args
is_component_build = false
is_debug = false
strip_absolute_paths_from_debug_symbols = true
- Run
third_party/blink/tools/run_web_tests.py --additional-expectations third_party/blink/web_tests/LeakExpectations --time-out-ms 48000 --enable-leak-detection external/wpt/wasm/webapi/body.any.html

8927256551 [wasm] Fix source positions for rethrown exceptions.
This fixes the source position printed in the stack trace for exceptions
rethrown from within Wasm code. This only affects the message propagated
to the console, not the trace stored as part of the exception object.

Note that there still is a more fundamental issues with preserving the
original message of a caught exception and funneling it through to each
rethrow site, which is still missing. This change just makes sure that
the interpreter and TurboFan are consistent.

  allocated when there are private name declaration or access in the
  class.

ab24897cb0 [fni] Mark computed props as computed, not anonymous function
I thought about potentially adding the identifer ref to the error but
that would require allocating a new string or at the very least
increasing the size of the resulting cons string. Given that the
parser is pretty performance sensitive, I've decided to not display
the identifier.

Previously, the error was:
  _test.js:3: Error
  a[foo].c = () => { throw Error(); };
                     ^
  Error
    at a.(anonymous function).c (_test.js:3:26)
    at _test.js:5:1

With this patch, the error becomes:
  _test.js:3: Error
  a[foo].c = () => { throw Error(); };
                     ^
  Error
    at a.<computed>.c (_test.js:3:26)
    at _test.js:5:1

7f92ad0ab6 [test] refactor testsuite configuration
Every testsuite configuration consist of at least 30% code duplication.

The code age ranges from 10 years old to 5 years old. Implementing anything that
touches the testsuite code becomes a technical fight to the death.

This CL removes all the duplication by refactoring the common functionality.

This CL contains structural changes without any logical changes % small bug
fixes.

892d322432 [d8] Catch errors in any message
Currently, errors somewhere deep in a promise chain are not reported as
test failures. We would print the error, but still return with exit
status 0. This CL fixes this to treat any uncaught exception as
failure, as we already do in {Shell::ExecuteString}.

08f68102f8 [parser] Allow declaring variables without a proxy
Declare Variables with a name and position, rather than by passing
through a VariableProxy. This allows us to not create dummy proxies
for things like function declarations, and allows us to consider those
declarations unused.

As a side-effect, we also have to check if a variable is unused in the
bytecode generator (as it will no longer be allocated), and we end up
skip generating code/SFIs for dead variables/functions.

6962334df8 [platform] Allow to memory-map empty files
This current fails, since {mmap} fails with EINVAL for empty mappings.
The destructor already has special handling for a {nullptr} mapping, so
we can just use {nullptr} for empty files. We get a similar error on
windows, and can fix it the same way.

On order to make presubmit checks happy, we have to skip copyright
checking and checking for terminating newlines for empty files.

c45850cd1e [parser] Declare variables through ExpressionScope
Use variable tracking from ExpressionScopes rather than the PatternRewriter and
PreParserExpression::variables_ to declare variables.

We only figure out that variables are non-simple parameters once we see the
first non-simple parameter. This still uses the pattern rewriter to make
variables non-simple (kLet instead of kVar).

928417997c [parser] Declarations store Variables not proxies
Storing a VariableProxy in declarations means that a declaration and
initialisation assignment are tightly coupled to use the same var. In
particular, this means that Var declarations in with scopes have to
clone the VariableProxy to split the declaration and initializer LHS
lookup.

This patch changes declarations to point directly to the Variable, not
the VariableProxy. This will allow future refactoring to decouple
declarations and initialisations.

b00ef71370 [nojit] Add a few flag implications based on --jitless
--jitless -> --no-opt

                                  -> --no-wasm-lazy-compilation

Note that wasm still isn't supported in jitless mode since it generates
code at runtime even with --wasm-interpret-all.

Drive-by: Fail early when trying to compile irregexp code in jitless
mode.
