0acbcf9876 Reland "Add out-of-line constant pool support to Arm." 
This CL adds out-of-line constant pool support to Arm.  A ConstantPoolBuilder
object is introduced to manage building of the ConstantPoolArray for a given

611ea747ef A64: Handle a few TODOs. 
Below are notes about some of the TODOs handled.

* In Simulator::Debug:
    We haven't had issues with printing in the debugger for a while. If the
    feature turns out to be still lacking an issue can be raised.

* In SubStringStub::Generate:
    There is no need to jump there. The StringCharAtGenerator is asked to set
    the result in x0, and the return sequence following only uses two instructions.
    Also, we would need to jump after the native counter increment instead of the
    return_x0 label.

* In ArrayPushStub::Generate:
    Raised an internal issue to check and update the ARM code.

* In MacroAssembler::CopyBytes:
    The new code should be faster for bulk copies. Raised an internal issue to
    investigate and improve this function.

* In MacroAssembler::EnterExitFrame:
    Unless we actually find something is wrong, this is working and looks ok.
    Also fixed the comments about the FP registers.

* Comment for BumpSystemStackPointer:
    Removed the comment at the declaration site and updated the TODO in the
    implementation.

f5f67ca58e Expose DumpBacktrace for debugging purposes. 
After this change, you can just call DumpBacktrace in any function. Previously
the only function printing stack traces was V8_Fatal, but that also terminated
the program, so not very useful for debugging.

Note that DumpBacktrace is roughly equivalent to base::debug::StackTrace
functionality in Chromium, except less fancy, but it's enough for us.

This patch includes 3 fixes for veneers emission.

1) Block veneer pools emission in the PatchingAssembler.
2) Fix the check for veneer pool emission just before a constant pool.
3) Forbid copy of labels. The list of JumpTableEntry used to track the
   deoptimization table entries would make copies of the labels when growing.
   Doing so, it would confuse the Assembler that was tracking the labels via
   pointers.

c45043881c Speed up A64 simulator by removing useless memcpy. 
The addresses involved should always be aligned, so we can simply use
a cast, just like the ARM simulator. Even if the alignment assumption
did not hold and the platform we are running on couldn't handle
unaligned access, some #ifdefs would be much more preferable. The
affected member functions were the top 2 in a profile (18% and 15%),
so basically every hack is allowed here to speed things up. :-)

Removed some dead code for literals on the way. If we need to
resurrect it, we should do it without double(!) memcpys.

Generally, I still don't understand why we need the Instr/Instruction
distinction or simply wrap Instr within Instruction, this seems to
be much simpler and cleaner, but this would involve heavier changes.

The overall speedup of this CL is roughly 37%, see the numbers below

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.

6923d84785 New Compilation API, part 1, try 2 
- Distinguish between context bound scripts (Script) and context unbound scripts
(UnboundScript).
- Add ScriptCompiler (which will later contain functions for async compilation).

This is a breaking change, in particular, Script::New no longer exists (it is
replaced by ScriptCompiler::CompileUnbound). Script::Compile remains as a
backwards-compatible shorthand for ScriptCompiler::Compile.

Passing CompilerOptions with produce_data_to_cache = true doesn't do anything
yet; the only way to generate the data to cache is the old preparsing API. (To
be fixed in the next version.)

This is a fixed version of https://codereview.chromium.org/186723005/

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.

- Distinguish between context bound scripts (Script) and context unbound scripts

- Add ScriptCompiler (which will later contain functions for async compilation).

This is a breaking change, in particular, Script::New no longer exists (it is
replaced by ScriptCompiler::CompileUnbound). Script::Compile remains as a
backwards-compatible shorthand for ScriptCompiler::Compile.

Passing CompilerOptions with produce_data_to_cache = true doesn't do anything
yet; the only way to generate the data to cache is the old preparsing API. (To
be fixed in the next version.)

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.

ReportUnexpectedToken already calls Traits::ReportMessageAt. If we're in Parser,
that already suppresses the syntax error. If we're in PreParser, we don't need
to suppress the syntax error (preparser errors don't go through Isolate, and
having both stack overflow and a syntax error present is handled correctly by
PreParserApi::PreParse).

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)

b69960070c Parser: fix confusion when there are multiple errors to report. 
(For more details, see bug.)

The problem occurs when a parsing function hits a stack overflow, but still
manages to return something meaningful. This happens because the call to
ParserBase::Next() which hits the stack overflow will still return a valid token
(the last token which we had already read), and only the next call after the
stack overflow will return INVALID. So for example ParseIdentifier will still
return a valid identifier even if we've hit a stack overflow.

In this case, some upper recursion level might detect and report a valid syntax
error, and then we bail out of the recursive descent because of the syntax
error. So we end up having both stack overflow and a syntax error present. When
we try to report the stack overflow after parsing (e.g., end of ParseLazy), the
isolate already has the syntax error as a pending exception, and a CHECK fails.

This fix suppresses the syntax errors in when a stack overflow has been
detected.

9cfd807cba Special case the recording of constant pool entries in the slot buffer. 
This CL enables RelocInfo pointers which live in the constant pool to be treated
as normal pointers by the slot buffer, avoiding the requirement of creating fake
RelocInfo objects during UpdateSlots() in order to update these slots.  This
is possible because constant pool entries are just pointers and don't require
the RelocInfo machinary to be updated.

EmbeddedObject constant pool entries can be added untyped to the slot buffer,
while code targets are still typed in order to correctly update the target
address based on the relocated code object.

Note: this is required in order to enable OOL constant pool support on Arm, but
should be benifitial for the current inline constant pool used by Arm code.

d625eb34be Deal with filler object map pointers in the ool constant pool correctly. 
This CL updates
StoreBuffer::FindPointersToNewSpaceOnPage such that it skips  constant pool array objects.  Constant Pool Arrays should never have pointers to the new space and might contain pointers to the FreeSpace map (e.g., due to code
being generated which needs to do a map-check on a FreeSpace object) which would incorrectly treated as a filler object if processed by FindPointersToNewSpaceOnPage().

This replaces Tmp0() and Tmp1() with a more flexible scratch register

We no longer have to worry about whether to use Tmp0(), Tmp1() or
