Message tests check the output of a test against an expected file.
Executing with --stress-opt changes the output, since the test will be
run multiple times. For that reason, most message tests explicitly add
the --no-stress-opt flag.
Since this is redundant, and not a per-test setting, just configure this
globally for all message tests instead.

In assignments the lhs should be evaluated first and shouldn't be
re-evaluated when the value of the rhs is available. Fix it by
saving the receiver and the key registers into AssignmentLhsData
before building the assignment and use them later, instead of visiting
the AST again to retrieve the receiver.
In addition, now that we save the receiver register, use it to
perform the brand check even when we know for sure that it's
going to fail later because it's a write to a private
method or accessing the accessor in the wrong way (v8:11364),
so that the brand check error always appears first if it is present,
as specified in
https://tc39.es/proposal-private-methods/#sec-privatefieldget
Drive-by: unify the brand check error messages, and replace "Object"
with "Receiver" in the messages for clarity. The instance private
brand check now throws "Receiver must be an instance of class <name>"
and the static private brand check now throws "Receiver must be
class <name>". Also always set the expression position to the
property load position, because the brand check failure comes from
the load operation.

Previously V8 was reusing the error fur duplicate declarations, using
the private name for class fields or the class name for class methods
as the redeclared identifier.
class A { constructor(o) { return o } }
class B extends A { #x }
class C extends A { #x() {} }
let D = (0, class extends A { #x() {} });
new B(new B({})) // Identifier '#x' has already been declared
new C(new C({})) // Identifier 'C' has already been declared
new D(new D({})) // Identifier '' has already been declared
This patch changes it to use error messages that better explain what's
happening:
new B(new B({})) // Cannot initialize #x twice on the same object
new C(new C({})) // Cannot initialize private methods of
// class C twice on the same object
new D(new D({})) // Cannot initialize private methods of
// class anonymous twice on the same object
I initially tried to use the same message for both fields and methods,
but the problem with that is that when initializing fields we only
have access to the field name, while when initializing methods we only
have access to the class name (using the "private brand" symbol).
However, almost all the error messages are different for private fields
and for methods so this shouldn't be a problem.

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:
> 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.

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).

Instead of {func-index}+{pc of instruction relative to function}, make
it {func-index}:{pc of instruction in module}. This is more consistent
with existing conventions
(https://webassembly.github.io/spec/web-api/index.html#conventions) and
other tools (like output of wasm-objdump).

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.

Simd unsupported in simulator and some machines on mips.
Original Commit Message:
As of https://crrev.com/c/2629465, Simd tests cannot pass on
architectures without Simd support. Tests will need to be
re-enabled once Simd support is fully implemented on PPC.

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.

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.

First step towards the new exception handling proposal:
https://github.com/WebAssembly/exception-handling/issues/125
This is essentially a revert of:
"[wasm] Switch to new 'catch' and 'br_on_exn' proposal."
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
