This CL does the first baby steps on moving the current (experimental)
exception handling to match that of the WebAssembly proposal.
It does the following:
1) Use exception tags instead of integers.
2) Only handle empty exception signatures (i.e. no values associated
with the exception tag.
3) Only handle one catch clause.
4) Be sure to rethrow the exception if the exception tag does not match.
Note: There are many things that need to be fixed, and are too
numerous to list here. However, the code should have TODO's on each
missing parts of the implementation.
Also note that the code currently doesn't handle nested catch blocks,
nor does it change the throw value being an integer. Rather, the
integer value is still being thrown, and currently is the exception
tag. Therefore, we don't build an exception object. This is the reason
why this CL doesn't handle exceptions that pass values.
Also, the current implementation still can't handle multiple modules
because tag resolution (between) modules has not be implemented yet.

Remove opt_count from SFI, which only had two real uses:
1. Detecting OSR in tests -- replaced with a stack walk in
%GetOptimizationStatus
2. Naming optimization log files -- replaced with the
optimization id
This allows us to remove a field from the SFI, moving the
bailout reason into the counters field.
As a drive-by, add optimization marker information (e.g.
marked for optimization) to the optimization status.

The tail call implementation is hidden behind the --harmony-tailcalls

It is known to be broken in a variety of cases, including clusterfuzz
security issues (see sample Chromium issues below). To avoid letting
the implementation bitrot further on trunk, this patch removes it.

Adds missing opcodes for exception handling for the function body decoder.
Also adds error messages if the exception handling construct is not yet
functional.
Note that the previous prototype for catch and throw have been marked
as not yet functional. This was done because it doesn't model
exceptions the way the proposal suggests. Rather, they implement a
hard-coded (c++ model) of exceptions.

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 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()

We create a new ASTNode so that we can pass the JSFunction closure() to
the runtime function from which we get the script_url.
d8 implements the embedder logic required to load and evaluate the modules.
The API is mostly implemented as specified.

This revealed a bug in the TypedArray(typedArray) constructor when the arg is backed by a SharedArrayBuffer.
Also install the species getter and add a test, since it's not tested in
test262 presently.

This fixes a corner case which allowed warnings during the asm.js
instantiation to be promoted to actual exceptions. Even instantiation
attempts that fail are not allowed to throw exceptions observable by
JavaScript, but need to fall back to JavaScript execution.

This extends the test coverage for source position tracking of ToNumber
conversion to also test conversion to "double" type. It also fixes the
discovered inconsistencies. Note that the conversion to "float" remains
untested as imported functions are not allowed have "float" return type.

This adds test coverage for the source position tracking of function
table calls in asm.js and fixes the discovered issues. It also fixes
function start positions (used by errors thrown at stack checks).
