Unlike previous implementation where the 'continue' keyword was a feature of a return statement the keyword is now recognized as a part of expression. Error reporting was significantly improved.
--harmony-explicit-tailcalls option is now orthogonal to --harmony-tailcalls so we can test both modes at the same time.
This CL also adds %GetExceptionDetails(exception) that fetches hidden |start_pos| and |end_pos| values from the exception object.

Yield expressions are not allowed in formal parameter initializers of
generators, but we weren't properly catching the case where the yield
expression appeared in the 'extends' clause of a class expression.
They also aren't allowed in arrow functions, which we were failing to
catch due to not looking at the obscurely-named "FormalParameterInitializerError"
bit of ExpressionClassifier.
This patch passes along an ExpressionClassifier when parsing class
expressions and accumulates the proper error for that case.
For the arrow function case, the fix is simply to check for the
"formal parameter initializer" error once we know we've parsed
an arrow function. The error message used for this has also
been made specific to yield expressions.
Tests are added both for the error case and the non-error cases (where
yield is used in such a position inside the class body).

The parser uses a try-catch in order to record when the client of an iterator
throws. The exception then used to get rethrown via 'throw', which
unfortunately resulted in the original exception message object getting
overwritten.
This CL solves this as follows:
- add a clear_pending_message flag to TryCatchStatement (set to true in normal
cases),
- set clear_pending_message to false for the TryCatchStatement used in iterator
finalization
- change full-codegen, turbofan, and the interpreter to emit the ClearPendingMessage call
only when the flag is set,
- replace 'throw' with '%ReThrow' in the iterator finalization code, thus
reusing the (not-cleared) pending message

Now that ES2015 const has shipped, in Chrome 49, legacy const declarations
are no more. This lets us remove a bunch of code from many parts of the
codebase.
In this patch, I remove parser support for generating legacy const variables
from const declarations. This also removes the special "illegal declaration"
bit from Scope, which has ripples into all compiler backends.
Also gone are any tests which relied on legacy const declarations.
Note that we do still generate a Variable in mode CONST_LEGACY in one case:
function name bindings in sloppy mode. The likely fix there is to add a new
Variable::Kind for this case and handle it appropriately for stores in each
backend, but I leave that for a later patch to make this one completely
subtractive.

test262 "negative" test expectations list which exception is thrown. The ES2017
draft specification is very specific about which exception class is thrown
from which path, and V8 works hard to be correct with respect to that spec.
Previously, the test262 test runner would accept any nonzero status code,
such as from a crash, or a FAIL printed out, for a negative test. This
patch makes negative tests check for the right answer using a quick-and-dirty
parsing of the exception printing from d8 to find the exception class.
It invokes d8 in a way to get a status code of 0 from thrown exceptions
so that 'negative' tests aren't actually implemented by negating the output.
Amazingly, this didn't catch any test262 failures, but I verified the extra
checking interactively by changing a negative test to expect a different type
and saw it fail.

The first bug was that there are two different "initialization positions"
passed into PatternRewriter::DeclareAndInitializeVariables, and we weren't
setting them all properly for this case.
After further code review, it became clear that we weren't even recording
the correct position (the end of the initializer expression).
The combination of those two bugs caused the hole check elimination code
in full-codegen to skip emitting a hole check.
This patch takes care of both of those things. A follow-up will try
to reduce the number of "initializer positions" we track in the
variable declaration code.

For web compat reasons, we support an initializer in the declaration
part of a for-in loop. But we should disallow this for destructured
declarations (just as we do for lexical declarations). In fact, without
disallowing it, we crash.
Also fix up the PreParser to have the same restrictions here as the parser
(the lexical check was missing there), verified by running the message tests
with --min-preparse-length=0.
In fixing the logic I've also cleaned up the code a bit, removing the
only-called-once DeclarationParsingResult::SingleName method.

Add() becomes AddLocalExport, which takes an export_name and a local_name.
New parsing tests exercise this.
Also start generating exports for default exports (though this doesn't yet
handle anonymous default exports).

This CL fixes tests that no longer valid and also fixes two issues:
1. 'super()' in non derived constructors.
2. Failure to step into derived constructors.

Replace the 'unable_to_parse' key used in three places with three difference keys.
Provide three more informative and less ambiguous error messages in place of 'Parse error'.
Add three test/message cases to cover the new messages.

Because we run all tests three times with different variant flags (to
test crankshaft) we might end up in a situation where we try to write
to the same serilization file from two different threads
simultaneously. The patch concats the variant flags at the end of the
serialization file name.

This patch enables two new flags for the tools/test.py script;
--shard-count - giving the ability to split the tests to be run
into shard-count chunks.
--shard-run - giving the ability to specify which of the shards to actually run.
Example
tools/test.py -j15 --shard-count=2 --shard-run=1 mozilla
would split the mozilla tests into two chunks and run the tests in the first chunk
Running:
tools/test.py -j15 --shard-count=2 --shard-run=1 mozilla
tools/test.py -j15 --shard-count=2 --shard-run=2 mozilla
is equivalent (in terms of test coverage) of just running:
tools/test.py -j15 mozilla
In addition, tests are now sorted before they are returned from the
test specific ListTests methods (sputnik and mozilla tests where
already sorted before they where returned).
This change is needed to split a single test suite over two slaves on
the waterfall.

- String traversal test data (now in a zone)
- Debug message thread (now joined on exit)
- Threading test threads (now joined on exit)
- Changed message tests framework to cope with valgrind
Also, fixed a bug where we'd try to delete stack-allocated objects
when tearing down v8. Good times.

report the exception when they happen in the try block and not as previously
when re-thrown after execution of the finally block. There is no longer any
message generated by re-throw.
Added test cases for various combinations of try/catch/finally with throw in
different places.
Added a regression directory to the messages tests which is processed by the
test runner.
Added regression tests for the specific bugs fixed.
Runs all the test suites.
