This proposal has not moved beyoned stage 2 in two years, and has never
moved past the HARMONY_INPROGRESS state in flag-definitions.h.

It was originally added to aide in desugaring yield*, but is no longer
used for that purpose.

5a68df2ab5 Remove support for unused compile options.
We don't use parser caches anymore and request code caches
explicitly using ScriptCompiler::CreateCodeCache. Hence
removing the support for both parser cache and code cache options.
They are still retained in CompileOptions for backwards
compatibility. Apart from the api.cc, no other part should see
this option.

3825d79620 [class] Throw error on accessing invalid private fields
Report an error during scope analysis if we're unable to find a
variable proxy for the given private field. This can happen if we try
to access a private field that was not defined or if we're outside
the class scope.

This doesn't correctly throw an early error when pre parsing a top
level function because we don't track it's variables.

2203a37c5d Replace CHECK(false) by UNREACHABLE()
... or sometimes by FATAL(...) to give a better error message.
The benefit of UNREACHABLE() over CHECK(false) is that the compiler
knows that this macro will never return, hence we can omit the return
of a dummy value afterwards.

Also, refactor the FATAL macro and use it for implementing UNREACHABLE
and UNIMPLEMENTED, and in more code. The benefit over printf +
CHECK(false) is that the compiler knows that FATAL will never return.

When preparsing top-level functions in a module, we didn't track

This patch fixes that. This also lets us stop forcing context

822be9b238 Normalize casing of hexadecimal digits
This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.

Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.

Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters

Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

94a71d7c45 [parser] Skipping inner funcs: accurately record NeedsHomeObject
Inner functions which called eval, and were the kind of functions
that can use `super`, were erroneously not marked as "uses_super_property",
leading to downstream crashes when the runtime tried to load the
[[HomeObject]] from them.

This patch eliminates the public Scope::uses_super_property()
API and ensures that callers always call Scope::NeedsHomeObject()
instead.

This is a minimal fix designed for easy merging; it's likely that
in the long run we should remove most mentions of "uses super property"
and replace them with "needs home object" for clarity.

d3c9812143 [parser] Add use counter for U+2028 & U+2029
The context is the following proposal to make JSON a subset of
JavaScript: https://github.com/tc39/proposal-json-superset

There’s interest in performing a side investigation to answer the
question of what would happen if we stopped treating U+2028 and U+2029
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
that data.

fe598532ec Pass Isolate pointer to String::Utf8Value/Value constructors
As part of J2V8 development (https://github.com/eclipsesource/J2V8),
we realized that we had a subtle bug in how Isolate scope was created
and it's lifetime managed, see:
https://github.com/eclipsesource/J2V8/issues/313.

Mentioned above bug was fixed, however, what we also noticed is that
V8 API has been constantly and slowly moving to such an API, in which
one has to pass Isolate explicitly to methods and/or constructors. We
found two more places that might have been overlooked. This contribution
adds passing of Isolate pointer explicitly to constructors of
String::Utf8Value and String::Value classes.

1bc0195231 [Parsing] Always pass a valid character-stream into the parser
Changes the contract of the parser to have a valid character stream passed
in the ParseInfo rather than the current situation where either:
 - it is passed explicitly (e.g., for streaming scripts)
 - a Script is passed and a character stream is created for this
 - or a source and encoding is passed in ParseInfo and the character stream
   is created from this.

The parse info also now owns the character stream (in a unique_ptr). It
can be destroyed using a new ResetCharacterStream() function. This will
enable the character stream to be kept live if any functions are asm.js
modules which were parsed, in order to be reused by the asm.js parser.
