Different Intl features (DateTimeFormat, NumberFormat, etc) have
different lists of locales supported. Previously, the default locale
was set to "und", as opposed to what was detected from the surrounding
system, if any of these features was missing data. With this patch,
only that feature is set to "und". In this way, the data quality should
be just as good as if there were no fallback logic, but at the same time,
resolvedOptions().locale should show the locale actually in effect.

This fixes source position tracking within the "increment" expression of
a for-statement. The old {StashCode} method was inherently incompatible
with side tables like the source position table, as it would leave them
untouched while mutating the bytecode stream. It was hence trimmed down
to {DeleteCode}.

This patch implements a timezone backend which is based on ICU, rather
than operating system calls. It can be turned on by passing the
--icu-timezone-data flag. The goal here is to take advantage of ICU's
data, which is more complete than the data that some system calls expose.
For example, without any special code, this patch fixes the time zone
of Lord Howe Island to have a correct 30 minute DST offset, rather than
60 minutes as the OS backends assume it to have.
Unfortunately, the parenthized timezone name in Date.prototype.toString()
differs across platforms. This patch chooses the long timezone name,
which matches Windows behavior and might be the most intelligible, but
the web compatibility impact is unclear.

* Make the scanner retain stale newline state on a rewind (as otherwise it must be able to correctly rewind that too, though it doesn't need it). (Probably should revisit).
* Change StashCode in the builder skip to the zero case, as it crashes for some reason (added TODO).
Also fix:
* Drop test based on constant expression evaluation in main parser
* Support constant defined based on existing constant.
* Type constants as signed.
* Added a check that all used functions are defined eventually.
* Zone allocate strings for simplicity (TODOs to refactor better).

This adds a --stress-validate-asm flag intended to stress test the
validator by running against every single function, independent of
whether a "use asm" directive is present. It mainly tests negative

The function "foo" in "base_getter_test" was picking up a left-over
optimised code object from foo's code map, the third time that
base_getter_test was run, instead of optimising it itself. This
broke the assumptions of the test, that each case was functionally
independent from the others, and had started off with empty feedback
and no optimised code.
This breaks the test though, so we have to blacklist it pending a fix
to the root cause (http://crbug.com/v8/6101).
