FINAL implies OVERRIDE, which in turn implies virtual, so there's no need to use

EmitCreateIteratorResult loads map from function's context
Caching or serialization can cause full-codegen output to be shared

thing by creating results with the map that was current when the code
was generated. Instead, we should chase pointers to load the right map
from the function's context.

The test mjsunit/regress/regress-sqrt compares the result of Math.sqrt function
when using full-compiler and crankshaft compiler seperately. But according to
glibc bug fixing(https://sourceware.org/bugzilla/show_bug.cgi?id=14032 ). The
glibc implementation of std::sqrt() (It is invoked in the generated code when
full-compiler is used.) will change since glibc 2.19.
In order to keep consistence of Math.sqrt translation in crankshaft compiler
and the pass of mjsunit/regress/regress-sqrt. we translate the Math.sqrt func
by calling the runtime function.

Removed superfluous deopt for ROR on ia32.
We only synthesize a ROR when we have an expression with a toplevel

negative values is not needed. ia32 was the only platform where this
was done, all other didn't have the check.

port r24123. R24123 does not cover all required code change in X87.
original commit message:
Further improve deopt reason output.
* Make the detailed deopt reason mandatory on x64, other platforms will
follow in separate CLs.
* Extracted and improved jump table entry sharing logic: When --trace-deopt
is on, we get separate entries for different deopt reasons. This enables
us to distinguish the several reasons single instructions can have.
* Don't emit superfluous jump table comments: The bailout ID is still visible,
and the jump table entry number is not interesting (but easy to determine
if really needed).
* Unify the internal name of the jump table member across platforms.

Further improve deopt reason output.
...
* Make the detailed deopt reason mandatory on x64, other platforms
will follow in separate CLs.
* Extracted and improved jump table entry sharing logic: When
--trace-deopt is on, we get separate entries for different deopt
reasons. This enables us to distinguish the several reasons single
instructions can have.
* Don't emit superfluous jump table comments: The bailout ID is still
visible, and the jump table entry number is not interesting (but
easy to determine if really needed).
* Unify the internal name of the jump table member across platforms.

This is a purely mechanical refactoring and a first step towards being
able to report more helpful deoptimization reasons. With this
refactoring, we know at least the mnemonic of the instruction causing
the deopt, although this is not used yet. Future steps will be using
the mnemonic, passing additional explicit deopt reasons and removing
the fragile machinery of searching for code comments.

Fixed deopt reasons in TaggedToI.
...
Every DeoptimizeIf should be preceded by a RecordComment explaining
the reason. In the long run, the reason should be an argument of
DeoptimizeIf, but we're not there yet.
On x87, things are a bit ugly due to some pushing/popping, so if
somebody feels inclined to improve this: Feel free. Probably the right
approach would be reloading instead of the push/pop horror.
Another thing is our inconsistent handling of the "done" continuation
of deferred code on the various platforms, I made tiny changes on the
way, but this should better be unified somehow, with all those
micro-optimizations removed.

Added CallInterfaceDescriptors to all code stubs. A handful

* Defined static Register methods for some of the new
CallInterfaceDescriptors. We could go a lot further here, but
it doesn't have to be done immediately.
* Added Representation arrays to some CallInterfaceDescriptors,
especially where future hydrogen versions of the stubs could
benefit from this knowledge.

Replace our homegrown ARRAY_SIZE() with Chrome's arraysize().

Our own ARRAY_SIZE() was pretty bad at error checking. If you use

Fix deoptimization address patching in Turbofan to use safepoints.
...
Since the deopt patch address needs to be available during GC to
resolve safepoints, we need to move it to the code object (instead of
the deoptimization input data) - accessing a separate fixed array
is not safe during GC. This CL adds a deoptimization_pc field to
each safepoint. The fields points to the deoptimization block.
The CL also fixes wrong register allocator constraints for
frame states on calls. These should always live on the stack
because registers are not preserved during a call.

port r22379
original commit message:
This CL simplifies var / const by ensuring the behavior is consistent in itself,
and with regular JS semantics; between regular var/const and eval-ed var/const.
Legacy const is changed so that a declaration declares a configurable, but non-writable, slot,
and the initializer reconfigures it (when possible) to non-configurable non-writable. This
avoids the need for "the hole" as marker value in JSContextExtensionObjects and GlobalObjects.
Undefined is used instead.

X87: More OStreamsUse OStreams more often
...
port r22232
original commit message:
This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

X87: Start using OStreams.
...
port r22179
original commit message:
Note that until everything is OStream-based, there are a few places
where we have to do some impedance matching. A few accessors had to be
const-corrected on the way.

X87: KeyedLoadIC should have same register spec as LoadIC.
...
port r22103.
original commit message:
On arm, arm64 and x64 there is a different register specification between LoadIC and KeyedLoadIC.
It would be nicer if these are the same, allowing some key optimizations.
