b261213fcc Revert "Improve error messages for property access on null/undefined"
This reverts commit 24c626c1f7.

Reason for revert: Blocks V8 roll into Chromium (changed error messages cause tests to fail):
https://ci.chromium.org/p/chromium/builders/try/linux-rel/724109?

Original change's description:

> Only print the property name when accessing null/undefined if we can

> If we can't, omit the property name in the error message.

> E.g. undefined[{toString:()=>'a'}] doesn't print 'read property [object
> Object]' anymore, which was misleading since the property accessed would

24c626c1f7 Improve error messages for property access on null/undefined
Only print the property name when accessing null/undefined if we can
convert it to a string without causing side effects.
If we can't, omit the property name in the error message.
This should avoid confusion when the key is an object with toString().
E.g. undefined[{toString:()=>'a'}] doesn't print 'read property [object
Object]' anymore, which was misleading since the property accessed would
be 'a', but we can't evaluate the key without side effects.

e3f21e6ddd [wasm] Consider only function names from the name section.
As per WebAssembly Web API[1], the engine should only consider names
from the name section to synthesize function names in the context of
call stacks. We previously also added support to harvest the exports
table here in an attempt to improve the DevTools debugging experience,
but that needs a separate fix specifically for the inspector (which
should also take into account the imports to harvest names).

Changes:
- Remove TypeCheckBranchResult. Change TypeCheckBranch() to return bool.
  Refactor call sites to reflect this (decouple current code
  reachability check from type check).
- Unify TypeCheckBranch(), TypeCheckFallthrough(), and the type-checking
  part of Return() into TypeCheckStackAgainstMerge().
- Make sure all TypeCheck* functions are only called within VALIDATE.
- In graph-builder-interface, rename end_env -> merge_env to reflect
  its function for loops.
- Change expected error messages in some tests.

1813665413 [no-wasm] Skip wasm tests if wasm is disabled
This CL introduces a test runner flag to detect if webassembly has been
disabled. Since all tests that require wasm are alrady skipped in
lite mode, we introduce a has_webassembly flag for the test runner which
checks for v8_enable_webassembly=true and v8_enable_lite_mode=false.
As a drive-by, we also do not set the V8_ENABLE_WEBASSEMBLY
preprocessor flag if lite mode is enabled.

The status files are updated by splitting wasm tests from the
"lite_mode" section and checking for "not has_webassembly" instead.

Note that the v8_enable_webassembly=false configuration is not tested
on any bot currently, but I will make sure that all tests keep passing
on further changes in this configuration.

a09c076f00 [modules][api] Add version of HostImportModuleDynamically with import assertions
This change completes support for import assertions for dynamic import().

A new version of the HostImportModuleDynamically callback taking import
assertions is added to the public API. The name is very verbose; we
could consider removing the "ImportAssertions" part when the old API
is removed.

Bytecode generation is updated to pass the assertions, if present, to
Runtime_DynamicImportCall.

Isolate::RunHostImportModuleDynamicallyCallback extracts the assertions
from the options bag, filters out the assertions not present in the
list specified by the host in HostGetSupportedImportAssertions, and
sorts them by code point order of the keys per
https://tc39.es/proposal-import-assertions/#sec-import-call-runtime-semantics-evaluation.
The resulting array is passed to the host in the callback.

The changes are:
- "catch" instruction takes a tag immediate,
- "rethrow" instruction takes a label immediate,
- Add "catch_all" instruction,
- Remove "br_on_exn" instruction,
- Do not push exceptions on the stack, only the encoded values

0832a1093d Reland^5 "[flags] warn about contradictory flags"
This is a reland of 2000aea58a
Changes compared to last reland:
- Add rule in variants.py for --enable_experimental_regexp_engine.
- Make sure --abort-on-contradictory-flags works as well as --fuzzing
  to disable the checking for fuzzers, including for d8 flags.

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.
