c3c185c173 Make invalid LHSs a parse-time (reference) error
This is required by the spec. It also prevents crashes resulting from the attempt to read type feedback for the RHS of an invalid assignment which full codegen never actually allocated info for.

To do: check properly in preparser already.

cf43195d47 A64: Fix a few simulation inaccuracies.
- Return the correct NaN when an invalid operation generates a NaN.
  - When one or more operands are NaN, handle them as the processor
    would, prioritising signalling NaNs and making them quiet.
  - Fix fmadd and related instructions:
     - Fnmadd is fma(-n, m, -a), not -fma(n, m, a).
     - Some common libc implementations incorrectly implement fma for
       zero results, so work around these cases.
  - Replace some unreliable tests.

This patch also adds support for Default-NaN mode, since once all the
other work was done, it only required a couple of lines of code.
Default-NaN mode was used for an optimisation in ARM, and it should now
be possible to apply the same optimisation to A64.

dd28969c1c Continued fix for 351257. Reusing the feedback vector is too complex.
Attempting to re-use the type feedback vector stored in the
SharedFunctionInfo turns out to be difficult among the various cases.
It will be much easier to do this when deferred type feedback processing
is removed, as is in the works.

Created bug v8:3212 to track re-introducing the optimization of reusing
the type vector on recompile before optimization.

The CL also brings back the type vector on the SharedFunctionInfo.

713aa33f2a Fix of argument materialization of captured heap numbers.
The escape analysis calculates the number of slots in an object as
no-of-slots = object-size / pointer-size.  This gives 3 slots for
heap numbers on 32-bit architectures (one slot for the map, two for
the double value); however, my argument materialization code assumed
just two slots (map + value). Since Hydrogen allocates heap numbers
quite rarely, it is hard to produce a more meaningful repro than the
one provided by Clusterfuzz. Any suggestions are welcome.

The fix is simple - we just read out all extra slots (beyond the map
and the double) for heap numbers.

75ad285860 Implement PersistentValueMap, a map that stores UniquePersistent values.
This is preparatory work to get rid of UnsafePersistent in blink.

The previous version had to be reverted due to timeouts in win32/Debug: https://codereview.chromium.org/197173002/

The timeouts happened because the STL version on that platform contains sanity checking code which opens a 'debug window' in the GUI, patiently waiting for the user to click ok/cancel/somethirdoption. It turns out, the cause for that debug window was totally valid and the test had a use-after-free issue.

The 1st patch set is the code as before. The 2nd patch set contains the fix.

Related blink changes are here: https://codereview.chromium.org/180363004/

This patch is largely based on https://codereview.chromium.org/175503003/, with some methods added to support the blink change mentioned above.

021d9e778c Fix for bug 351257: type feedback vector initialization issue.
The feedback vector is stored in the shared function info, and there
is an effort to reuse it when re-running full code generation as a
prelude to creating optimized code. However we shouldn't reuse the
vector for lazily compiled methods on first compile, as scoping analysis
can change the allocation of vector slots.

7477bc39ca 350884: KeyedStoreIC miss didn't handle a transitioning case.
It's possible to get a transitioned map with no links to the origin
map if it's a shared map. Code in KeyedStoreIC::StoreElementStub
assumes it can check if two maps are in the same family by
traversing the transition array. Long term, the "family" relationship
should be recognized with the Normalized Map Cache. For now, allow
the IC to remain monomorphic in this case if the receiver map and
the previous receiver map are the same.

Filed V8 issue 3210 (https://code.google.com/p/v8/issues/detail?id=3210)
to track the issue with the Normalized Map Cache.

8bd37cb7c3 Refactor script compilation / running & use of helper funcs in test-api.cc.
The tests were using different kind of constructs for achieving the same
thing. This makes refactoring the compilation API more difficult than it should
be.

cctest.h already contained helpers for compiling and running scripts, but they
were not used consistently.

For example, all these were used for running scripts:

v8::Script::Compile(v8_str("foo"))->Run();
v8::Script::Compile(v8::String::NewFromUtf8(isolate, "foo))->Run();
CompileRun(v8_str("foo"));
CompileRun(v8::String::NewFromUtf8(some_way_to_get_isolate(), "foo"));
v8::Local<v8::Script> script = any_of_the_above; script->Run();

Most of the tests just want to run a script (which is in const char*) and don't
care about how the v8::String is constructed or passed to the compiler API. Using
the helpers makes the test more readable and reduces boilerplate code which is
unrelated to what the test is testing.

Notes:
- The regexp in the ParseObjectLiteralComment was wrong, made it less wrong (
it's still wrong since trailing commas are not required / allowed).
- Change in logic: In case we have "get somekeyword() { }", the "somekeyword"
was not logged as a symbol by PreParser and not expected in the preparser data
by Parser. This is unnecessary complication; in other contexts where keywords
are allowed as identifiers, they are logged as symbols (see
ParseIdentifierName).

33a46be689 A64: Handle a few TODOs.
Notes about a few TODOs handled in this patch:

* In ProfileEntryHookStub::Generate:
    Stubs are always called with relocation.

* In CreateArrayDispatchOneArgument:
    The branches to registers can't be conditional. We could use a jump table, but
    there are only 6 different kinds so it is likely not worth it.

* In Builtins::Generate_StringConstructCode:
    Rename the argc register (x0) after its meaning changes.
    Remove a TODO: using a macro would not make the code clearer.

* In Generate_JSEntryTrampolineHelper:
    Remove the TODO and raise an internal issue to investigate this.

* In Disassembler::SubstituteBranchTargetField:
    Print the target address, but we don't have more info on the target.

49cd3d8a65 Allocation tracker: add separate entry for allocations via V8 API
When object is creating via native V8 API calls JS callstack is empty and the allocation is indistinguishable from say compiler allocations. This change adds a separate entry for such allocations.

Since FunctionInfo not necessarily corresponds to a heap object they are now referred to using their index in the list of all FunctionInfos.

bd1fb97d5c Remove Script::SetData and the script_data parameter from Script::(Compile|New).
This feature makes it possible to associate data with a script and get it back
when the script is compiled or when an event is handled. It was historically
used by Chromium Dev Tools, but not any more. It is not used by node.js.

Note: this has nothing to do with the preparse data, despite the confusing name.
The preparse data is passed as ScriptData*.

Note 2: This is the same as r19616 ( https://codereview.chromium.org/184403002/ )
with a unused variable fix in bootstrapper.cc.
