Like CSP flag 'unsafe-eval', which communicates if both JS source
files and WASM binary files may be compiled, this CL adds a similar
flag for the compilation of WASM binary files.
That is, a WASM binary file will be compiled only if the new flag is
defined, or the flag for 'unsafe-eval' allows it. These flags are
implemented as callback functions on the isolate. The callbacks get a
(CSP) context, and a string, and returns the corresponding value of
the flag.
Both callbacks are initialized with the nullptr, and is used to
communicate that no CSP policy is defined. This allows this concept to
work, independent of it running in Chrome.
It also does a small clean up in api.cc to use macro CALLER_SETTERS,
instead of explicit code when appropriate.

Rather than having a single script compilation timer, split it into
multiple timers depending on the state of the (blink-owned) code cache
and (v8-owned) complation cache. This is intended to replace both the
script compilation time timer, and the compilation heuristic enum.
Also keep track of why blink might not want us to produce (or consume) a
code cache, and split the compilation timer on this as well.
Note, there is currently no timer for streaming sources, so these won't
show up in the histograms.

There’s interest in performing a side investigation to answer the

as `LineTerminator`s *entirely*. (Note that this is separate from the
proposal, which just changes how these characters are handled in
ECMAScript strings.) This is technically a breaking change, and IMHO it
would be wonderful if we could get away with it, but no one really has
any data on whether or not we could. Adding this use counter lets us get

In this implementation the decoding of sections other than the

Eventually all decoding should happen in the background. I
think it is acceptable to do the decoding on the foreground
thread for now because I have finished it already, and
decoding in the background would add even more complexity to

The V8 API provides interceptors. They are not part of the

For example, when an EnumeratorInterceptor is defined, Object.keys(),
Object.entries(), and Object.values() should all have the

This CL creates consistent behavior among these
functions. If a QueryCallback is present, it is used to
