394af55a8c Script streaming: more UTF-8 handing fixes (again). 
1) Since we fill the output buffer both from the chunks and the conversion
buffer, it's possible that we run out of space and call CopyCharsHelper with 0
length. The underlying functions don't handle it gracefully, so check there.

2) There was a bug where we used to try to copy too many characters from the
beginning of the data chunk into the conversion buffer. Continuation bytes in
UTF-8 are of the form 0b10XXXXXX. If a byte is bigger than that, it's the first
byte of a new UTF-8 character and we should ignore it.

These two together (or maybe in combination with surrogates) are a probable
reason for crbug.com/420932.

3) The test data was off; \uc481 is \xec\x92\x81.

This issue is for discussion on how to proceed.

I think the implementation of ValueOf shows that directly creating the IR does not scale.

e4c6f9488e Implement graph trimming in ControlReducer. 
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.

This CL is one half of the ControlReducer functionality, the other half
being branch folding.

0841f7241b Track usage of "this" and "arguments" in Scope 
This adds flags in Scope to track wheter a Scope uses "this" and,
"arguments". The information is exposed via Scope::uses_this(),
and Scope::uses_arguments(), respectively. Flags for tracking
usage on any inner scope uses are available as well via
Scope::inner_uses_this(), and Scope::inner_uses_arguments().

Knowing whether scopes use "this" and "arguments" will be handy
to generate the code needed to capture their values when generating
the code for arrow functions.

0e16150d33 Better typing and type verification 
- Extend verifier to check types of JS and Simplified nodes.
- Untyped nodes now contain NULL as types, enforcing hard failure.
- Typer immediately installs itself as a decorator; remove explicit decorator installation.
- Decorator eagerly types all nodes that have typed inputs
  (subsumes typing of constant cache, removing its typing
  side-channel and various spurious dependencies on the typer).
- Cut down typer interface to prevent inconsistently typed graphs.
- Remove verification from start, since it caused too much trouble
  with semi-wellformed nodes.
- Fix a couple of bugs on the way that got uncovered.

To do: verifying machine operators. Also, various conditions in the
verifier are currently commented out, because they don't yet hold.

0f5949d605 Fix scheduler to correctly schedule nested diamonds. 
The scheduler rewires control based on the last *control*
node that appears in the schedule of a block. This is not
sufficient to account for dependencies.

This patch adds additional dependencies to floating control
nodes. Given a floating control node A, every non-control
dependency of every node B that depends on A is introduces
as an additional dependency of A.

This allows the scheduler to correctly schedule two
diamonds A, B, if their only correct schedule is to
schedule B into the ifTrue successor in A.

363ac55a5d Script streaming: UTF-8 handling fix. 
The problem was that there can be several multi-byte UTF-8 characters near the
splitting point of the data chunks, and the code didn't handle it properly.

This was also the source of crbug.com/417891 - I thought the crash can only
happen when V8 is passed invalid UTF-8 data, but it can also happen in the
abovementioned case. After the fix, we handle the valid UTF-8 case and also
guard against invalid UTF-8 data.

a17289f4bc [turbofan] Drop broken StaticParameterTraits. 
The StaticParameterTraits are broken by design, and cause way too much
trouble. The compilers usually pick the wrong specialization (i.e. the
default specialization is picked for Load and Phi even tho there is a
specialization for MachineType), which is not only the reason why GVN is
ineffective and slow, but can also lead to correctness issues in some
rare cases.

Also clean up some minor bugs/inconsistencies on the way.

08c40baa1f Revert of Extend CPU profiler with mapping ticks to source lines (patchset #3 id:40001 of https://codereview.chromium.org/616963005/) 
Reason for revert:
It broke layout test fast/events/window-onerror-02.html, error column reported by window.onerror is now wrong (I believe it is because of the change in full-codegen):

http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2064%20%28dbg%29/builds/652

6482fb3ee4 Extend CPU profiler with mapping ticks to source lines 
The idea behind of this solution is to use the existing "relocation info" instead of consumption the CodeLinePosition events emitted by the V8 compilers.
During generation code and relocation info are generated simultaneously.
When code generation is done you each code object has associated "relocation info".
Relocation information lets V8 to mark interesting places in the generated code: the pointers that might need to be relocated (after garbage collection),
correspondences between the machine program counter and source locations for stack walking.

This patch:
1. Add more source positions info in reloc info to make it suitable for source level mapping.
The amount of data should not be increased dramatically because (1) V8 already marks interesting places in the generated code and
(2) V8 does not write redundant information (it writes a pair (pc_offset, pos) only if pos is changed and skips other).
I measured it on Octane benchmark - for unoptimized code the number of source positions may achieve 2x ('lin_solve' from NavierStokes benchmark).

2. When a sample happens, CPU profiler finds a code object by pc, then use its reloc info to match the sample to a source line.
If a source line is found that hit counter is increased by one for this line.

3. Add a new public V8 API to get the hit source lines by CDT CPU profiler.
Note that it's expected a minor patch in Blink to pack the source level info in JSON to be shown.

4.Add a test that checks how the samples are distributed through source lines.
It tests two cases: (1) relocation info created during code generation and (2) relocation info associated with precompiled function's version.

6a07181cde Refactor BasicBlock to not use GenericNode. 
To manage BasicBlock's predecessors and successors we now use plain
std::vector.

The change also moves bunch of method definitions from header files
to implementation files.

In zlib, the change brings 3x improvement in the scheduler's memory
consumption. The --turbo-stats flag says we go 169MB -> 55MB in
the scheduler, 383MB -> 268MB overall.

check that the handle is null and crashes the renderer.

27f3cc1b9c Require V8 to be explicitly initialized before an Isolate is created 
We also initialize the Isolate on creation.

This should allow for getting rid of the last remaining default isolate
traces. Also, it'll speed up several isolate related operations that no
longer require locks.

Embedders that relied on v8::Isolate to return an uninitialized Isolate
(so they can set ResourceConstraints for example, or set flags that
modify the way the isolate is created) should either do the setup before
creating the isolate, or use the recently added CreateParams to pass e.g.
ResourceConstraints.

069a9c75ad Move configuration of ResourceConstraints to Isolate construction 
We can only set resource constraints before the isolate is initialized.
Since in the future, we want to initialize isolates at construction
time, we need to set constraints there.

It's possible to later modify the stack limit, so introduce an
Isolate::SetStackLimit method for that.

The SetResourceConstraints method will be deprecated. Users should pass
ResourceConstraints to Isolate::New, and use Isolate::SetStackLimit to
later modify the stack limit.

65a1857824 Currently, a new isolate is created in an uninitialized state, and 
several API methods will automatically initialize it. During this
uninitialized state, code event handlers and function entry handlers can
be attached to the isolate.

This CL deprecates SetFunctionEntryHook and moves the configuration of
those handlers to the Isolate factory method.

This will allow for initializing the Isolate at creation time in the
future.

Users of V8::SetFunctionEntryHook should pass the entry hook to
Isolate::New instead. V8::SetJitCodeEventHandler should either be passed
to Isolate::New as well, or (if startup events are not required) invoked
via the Isolate.

00e90b7e6e Remove deoptimization by patching the call stack. 
We go back to patching the code for lazy deoptimization because ICs need the on-stack return address to read/update the IC address/state.

The change also fixes bunch of tests, mostly by adding more deoptimization points.

(We still need to add code to ensure lazy deopt patching does not overwrite ICs and other lazy deopts; this is coming next.)

Reland fixes:
 - size_t conversion for 64bit arches
 - Don't call front() on empty vector
   (triggers assertion on windows)
 - turbo_inlining now implies turbo_types, as
   it requires simplified lowering.

b3b4e3eea5 Fix deoptimization of context. 
We need to handle the case where the context was removed by dead code
elimination. In that case, we just use the context from the activation
(or from the inlined function if we are inlined).

For reference, here is the CL that introduced the bug: https://codereview.chromium.org/522873002

7955937d31 Refactor Parser to make it usable on a background thread. 
- Background Parsers cannot get the following data from Isolate (pass it to the
ctor instead): stack limit (background Parsers need a different stack limit),
UnicodeCache (background parsers need a separate UnicodeCache), hash seed
(Parser cannot access the Heap to get it). The Parser::Parse API won't change.

- Make the internalization phase (where Parser interacts with the heap) more
explicit. Previously, Parser was interacting with the heap here and there.

- Move HandleSourceURLComments out of DoParseProgram, so that background parsing
can use DoParseProgram too.
