X87: fix the Sqrt issue.
...
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.

X87: Further improve deopt reason output
...
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.

Simplify synthetic roots creation in heap snapshot
...
The synthetic roots exist in every snapshot and there are no actual objects corresponding to them (there was attempt to create some virtual objects to reuse existing snapshot builder but it just complicated the things).
Previously synthetic root wouldn't have been added if it was empty. Current implementation always adds all synthetic roots in the snapshot no matter if they are empty or not.

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.

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.

This is a purely mechanical refactoring and a first step towards being

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.

Removing ic.h from code-stubs.h
CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.
More work could/should be done here, but this is a first step.

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.

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.

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.)

original commit message:
Added CallInterfaceDescriptors to all code stubs. A handful
of code stubs are too complex to be described this way, and
they are encoded with the macro
DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR().
Along the way:
* allowed inheritance of CallInterfaceDescriptors.
* 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.

wrap the probe activity in a hydrogen instruction.

Improve x32 detection macro.
...
When targeting the Microsoft ABI in 64bit mode, clang defines __x86_64__ but
doesn't define __LP64__ (Microsoft uses LLP64), so it would fall down the x32
path. cl.exe doesn't define __x86_64__ in the first place, so it didn't have
this problem.
Rather than trying to guess pointer size by looking at __x86_64__ and __LP64__,
check for pointer size directly using __POINTER_SIZE__. This is defined by both
gcc and clang, and eliminiates this problem.
This should fix hundreds of "error(clang): unknown type name 'Atomic64'" when
compiling v8 on Windows with clang for 64 bit.
