590707184d MIPS: Refactor optimized in hydrogen only runtime functions. 
Port r20252 (d0f806b)

Original commit message:
This splits all runtime function into 3 categories:
1) RUNTIME: implemented in runtime and called from both full and optimized code.
2) RUNTIME_HIDDEN: implemented in runtime, never called directly from JS builtins.
3) INLINE: inlined in both full and optimized code
4) INLINE_OPTIMIZED: inlined in optimized code, implemented in runtime for full code.

25260c2b9a PreParser cleanup: no need to track with-ness of scopes. 
Historically, we used to track the "with-ness" of a scope differently; not
creating a with scope, but setting a property on the scope (see
https://codereview.chromium.org/5166006 ). For laziness decisions, checking the
with-ness should be unnecessary: the current scope is function scope, and if the
outer scope is global scope, there's surely no with scope in between.

Not V8_EXPORTing ScriptCompiler::Source got rid of the last errors. This fixes

586f64e1f3 Revert "Use constant length for memcpy on A64 simulator." 
This reverts commit r20141 which broke the build with some GCC versions. The
reason behind that is GCC emits a warning about code which can never be reached,
but GCC can't figure that out.

The right approach would be using template specialization instead of these
runtime if/then/else cascades, which would be nicer from a SW engineering
perspective, too.

e9358fa9ce Increase the "local variables in a function" limit. 
The limit was originally added to avoid having large user-controlled constants
(variable indexes) in the code generated by full-codegen.

History behind this change:

The original CL for adding the limit was https://codereview.chromium.org/7003030
and at that time, the limit was 32767.

Reason for adding the limit (in CL comments): "The motivation behind this change
is to avoid large user controlled constants in the code. The slot_operand used
in the IA32 full code generator uses a relative load where the local index is an
(negative) immediate."

The limit was then bumped to 65535 by https://codereview.chromium.org/10965063
and to 131071 by https://codereview.chromium.org/11099063.

a03e80c3a5 MIPS: Pretenure call new support. 
Port r20076 (b7b1372)

Original commit message:
When FLAG_pretenure_call_new is on, we emit mementos on new object creation
in full code, and consume the feedback in crankshaft. A key difference in the
generated code for stubs is the allocation of an additional type vector slot for the
CallNew AST node, which simplifies the CallConstructStub and CallFunctionStub
considerably.

Some performance tuning still needs to be addressed, therefore the flag is off at
this moment, though fully functional. The goal is to remove the flag as soon as
possible, which allows much code deletion (yay).

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.)

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.

StopCpuProfiling is replaced with StopProfiling which returns non-const CpuProfile which allows to call CpuProfile::Delete on it without const_cast. Also replaced StartCpuProfiling with StartProfiling to have symmetric names for start/stop actions.

52c0098f0d New Compilation API, part 1 
- 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.)

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.
