https://github.com/tc39/ecma262/pull/778 was recently merged
to Ecma 262.
It changes the way to convert between "local time" and UTC in such
a way that it'd work for all timezones whether or not there has
been any change in the timezone offset of the standard time. For
instance, Europe/Moscow and some parts of US state of Indiana have
changed the standard (non-DST) timezone offset a few times. The
previous spec assumes that the the standard timezone offset is
constant, but the new spec take into account the offset change
history.
In addition, it specifies a new way to calculate the timezone
offset during a timezone transition (either in and
out of DST or timezone offset shift).
During a negative transition (e.g. fall backward / getting
out of DST), repeated times are to be interpreted as if the
offset before the transition is in effect.
During a positive transition (e.g. spring forward / getting
into DST), skipped times are to be treated similarly. That
is, they are to be interpreted as if the offset before the
transition is in effect.
With icu-timezone-data, v8 is compliant to the new spec for the
past and the future as well as now whether or not the standard
timezone offset of a given timezone has changed over time
(e.g. Europe/Moscow, Pacific/Apia). With icu-timezone-data,
Australia/Lord_Howe (30 minute DST change) also works per spec.
Without icu-timezone-data, it works only for timezones of which
the standard timezone offset is the same as the current offset
(e.g. most North American timezones other than parts of Indiana)
and of which the DST shift is an hour. For instance, it doesn't work
for Europe/Moscow in 2010 when the standard timezone offset was
+4h because the current (2018) standard timezone offset is +3h. Neither
does it for Lord Howe in Australia with the DST shift of 0.5 hr.
This CL used to require one of the two ICU CLs below, but not

@@replace has a pretty complex implementation, taking different paths
for various situations (e.g.: global/nonglobal regexp, functional/string
replace argument, etc.). Each of these paths must implement similar
logic for calling into the RegExpBuiltinExec spec operation, and many
paths get this subtly wrong.
This CL fixes a couple of issues related to the way @@replace handles lastIndex:
* All paths now respect lastIndex when calling into exec (some used to assume 0).
* lastIndex is now advanced after a successful match for sticky regexps.
* lastIndex is now only reset to 0 on failure for sticky regexps.

ES2015 generally bans FunctionDeclarations in positions which expect a Statement,
as opposed to a StatementListItem, such as a FunctionDeclaration which constitutes
the body of a for loop. However, Annex B 3.2 and 3.4 make exceptions for labeled
function declarations and function declarations as the body of an if statement in
sloppy mode, in the latter case specifying that the semantics are as if the
function declaration occurred in a block. Chrome has historically permitted
further extensions, for the body of any flow control construct.
This patch addresses both the syntactic and semantic mismatches between V8 and
the spec. For the semantic mismatch, function declarations as the body of if
statements change from unconditionally hoisting in certain cases to acquiring
the sloppy mode function in block semantics (based on Annex B 3.3). For the
extra syntax permitted, this patch adds a flag,
--harmony-restrictive-declarations, which excludes disallowed function declaration
cases. A new UseCounter, LegacyFunctionDeclaration, is added to count how often
function declarations occur as the body of other constructs in sloppy mode. With
this patch, the code generally follows the form of the specification with respect
to parsing FunctionDeclarations, rather than allowing them in arbitrary Statement
positions, and makes it more clear where our extensions occur.

This patch doesn't ship all features of ES2015 variable/scoping
changes, notably omitting the removal of legacy const. I think
function hoisting, let and class in sloppy mode can stand to
themselves as a package, and the legacy const change is much
riskier and more likely to be reverted, so my intention is to
pursue those as a separate, follow-on patch.

Also fix CheckConflictingVarDeclarations() to properly handle
legacy const bindings. Without that change enabling the flag
causes code like:
function f() { const x; var x; }
to throw an early error, rather than wait to throw the error
until f is invoked.
The previous patch ran into problems with the fuzzer; that crash was fixed
(with test coverage added) in https://crrev.com/ceb92ebfdfb561d71038793c02b42aa973f55ec4

Remove some non-standard code that doesn't do anything anyways.
While FireFox uses this to set the default value for the multiline flag,
it is nonstandard and slated for removal. The matching behaviour has
never been implemented in either JSC or V8, so there is little
web-compat risk.
The only possible risk could be someone depending on the ToBoolean()
behaviour of the flag, but this seems unlikely.

This removes special casing for the 'f.arguments' property accessor. Any
local 'arguments' variable should not be allowed to influence the value
returned by the indirect 'f.arguments' property. That property creates a
new object with a separate identity everytime it is read. This is by now
consistent with other browsers.

This is non-standard and not even documented on MDN.
On Firefox, setting RegExp.multiline to true adds the multiline flag to all
newly created RegExp objects (both from constructor and from literal).
In V8 this has no effect.
