Instead, it is supposed to just return an empty context if it failed.
Also don't invoke interceptors (we don't for the parts that deserialize
from the snapshot anyways).

This internalization was not necessary, since the rewriting does not use
the .result name string.
The subsequent internalization is still needed, so to simplify later
refactoring, this CL also adds "releasing" of the disallow scopes and
uses them here immediately before the second internalize. Notably, this
means that the rewriting is now also in the disallow scopes.
Driveby: Remove isolate from the rewriter's processor constructor.

Creates an AstStringConstants container which pre-initializes the
string constants used by AstValueFactory. This ensures that all
AstValueFactories will produce the same AstValue objects for constants,
and so they can be used by the BytecodeGenerator without having to pass
the AstValueFactory to it, enabling construction off-thread.

A GC could happen when creating the Module string, which would cause the
JSModuleNamespace to be seen in an incomplete state. Instead make this
string a root object so that we don't need to allocate it during
NewJSModuleNamespace construction.

KillFields of an object should remove its cache from all the fields.
Currently, the cache in the front field is kept which is not expected.
This patch fixes it.

Our .clang-format is derived on the Google style, which sets
PointerAlignment to left (e.g. "Type* name"), but sets
DerivePointerAlignment to true. Once we started with the wrong style,
this made all new code in wasm-debug.cc use PointerAlignment=right,
resulting in lots of code using the wrong style.
For this CL, I ran
clang-format -style="{DerivePointerAlignment: false, BasedOnStyle: \
Google}" -i src/wasm/wasm-debug.cc

third_party/inspector_protocol is tracked in git and ignoring it causes
problems if the tree is copied to another git repository (e.g. Node.js)
Similarly, third_party/binutils has some files checked in. This adds a
.gitignore file in this directory (same as Chromium).

This removes usage of metadata files entirely. Instead we extract
the instrumentation about source files from the test cases.
This also adds extra output of the original source file in the
detailed failure text for easier debugging. The hashes alone
made it hard to reason.

code, that for these cases it runs on the main thread, and that for
non-top-level code it can safely be called off-thread.

The special treatment is not required anymore because the wasm spec
changed and NaNs do not have to be preserved anymore. In addition, it
may introduce non-determinism which confused the fuzzers.
