Clear optimized code cache in shared function info when code gets deoptimized.
...
This adds a pointer to the shared function info into deoptimization data of an optimized code. Whenever the code is deoptimized, it clears the cache in the shared function info.
This fixes the problem when the optimized function dies in new space GC before the code is deoptimized due to code dependency and before the optimized code cache is cleared in old space GC (see mjsunit/regress/regress-343609.js).
This partially reverts r19603 because we need to be able to evict specific code from the optimized code cache.

Make cells pointing to JSObjects weak in optimized code.

This is done similar to weak embedded objects in optimized code (r17102). The
reference from optimized code to a cell is treated weakly in marking visitors
if the cell points to a JSObject. After marking we iterate over all cells
embedded in optimized code. If a cell is not marked but its value is marked,
then we revive the cell by marking it. Otherwise, the cell value is dead, so
we mark the code for deoptimization.

The goal is to discover the appropriate heap space for objects created in full
...
code. By the time we optimize the code, we'll be able to decide on new or old
space based on the number of surviving objects after one or more gcs.
The mechanism is a "memento" placed behind objects in the heap. It's currently
done for array and object literals, with plans to use mementos for constructed
objects as well (in a later CL).
The feature is behind the flag allocation_site_pretenuring, currently off.

Move FindCodeObject from Heap to Isolate.
...
This removes the isolate=>heap=>isolate nonsense and has the additional bonus
that it re-enables printing of code objects in GDB. NOT: To make the latter
work, one has to adapt GDB any macros using FindCodeObject! Keeping things as it
is and outlining Isolate::heap() was not really an option...
Side note: Currently we are lucky that we still have Isolate::Current()
available in GDB, although it is marked as INLINE. :-}

Reland deprecation of HAllocateObject in favor of HAllocate.
...
This essentially relands r14930 and r14935 with adaptions to the current
code base. It models the instantiation of an implicit receiver for
CallNew nodes in hydrogen using HAllocate together with generic stores
instead of one specialized HAllocateObject instruction, hence creating a
single choking point for inlined allocation in optimized code.

Renamed "symbols" to "internalized strings" throughout the code base,

in preparation of the introduction of ES6 'symbols' (aka private/unique names).
The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders.
The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

Fix corner case when JSFunction is evicted from flusher.

This fixes a corner case that happens when JSFunctions are enqueued as
code flushing candidates but their respective SharedFunctionInfo isn't.
If the JSFunction gets evicted due to optimization the code slot in the
SharedFunctionInfo will never be recorded in the slots buffer.

Refactoring of snapshots. This simplifies and improves
...
the speed of deserializing code. The current startup
time improvement for V8 is around 6%, but code deserialization
is speeded up disproportionately, and we will soon have more
code in the snapshot.
* Removed support for deserializing into large object space.
The regular pages are 1Mbyte now and that is plenty. This
is a big simplification.
* Instead of reserving space for the snapshot we actually
allocate it now. This removes some special casing from
the memory management and simplifies deserialization since
we are just bumping a pointer rather than calling the
normal allocation routines during deserialization.
* Record in the snapshot how much we need to boot up and
allocate it instead of just assuming that allocations in
a new VM will always be linear.
* In the snapshot we always address an object as a negative
offset from the current allocation point. We used to
sometimes address from the start of the deserialized data,
but this is less useful now that we have good support for
roots and repetitions in the deserialization data.
* Code objects were previously deserialized (like other
objects) by alternating raw data (deserialized with memcpy)
and pointers (to external references, other objects, etc.).
Now we deserialize code objects with a single memcpy,
followed by a series of skips and pointers that partially
overwrite the code we memcopied out of the snapshot.
The skips are sometimes merged into the following
instruction in the deserialization data to reduce dispatch
time.
* Integers in the snapshot were stored in a variable length
format that gives a compact representation for small positive
integers. This is still the case, but the new encoding can
be decoded without branches or conditional instructions,
which is faster on a modern CPU.

Fix full code generator to not use --debug-code if it is in
...
mksnapshot or a VM that is booted from a snapshot. --debug-code
can still have an effect on stub and optimized code and it still
works on the full code generator when running without snapshots.
The deoptimizer generates full-code-generator code and relies on it having
the same layout as last time. This means that the code the full code
generator makes for the snapshot should be the same as the code it makes
later. This change makes the full code generator create more consistent
code between mksnapshot time and run time.
This is a bug fix and a step towards making the snapshot code more robust.

Separating transitions from descriptors.
...
In this design maps contain descriptor arrays, which in turn can contain transition arrays. If transitions are needed when no descriptor array is present, a descriptor array without real descriptors is inserted just so it can point at the transition array.
The transition array does not contain details about the field it transitions to. In order to weed out transitions to FIELDs from CONSTANT_FUNCTION (what used to be MAP_TRANSITION vs CONSTANT_TRANSITION), the transition needs to be followed and the details need to be looked up in the target map. CALLBACKS transitions are still easy to recognize since the transition targets are stored as an AccessorPair containing the maps, rather than the maps directly.
Currently AccessorPairs containing a transition and an accessor are shared between the descriptor array and the transition array. This simplifies lookup since we only have to look in one of both arrays. This will change in subsequent revisions, when descriptor arrays will become shared between multiple maps, since transitions cannot be shared.

This refactors the way we (re)define elements to perform normalization

bogus special cases in upper runtime layers.
Most element setters take an indicator flag that distinguishes between
setting and defining. Setting of an element causes attributes to remain
unchanged, writability to be checked and callbacks to be called.
Defining of an element causes attributes to be updated and callbacks to
be overridden. The same approach could be taken for properties.
