Previously, we would both instrument the code, and add/remove
BreakPointInfo objects through BreakLocation. This is bad design and
unsuitable for having two different code kinds.
We would now add/remove BreakPointInfo objects, and use that as source
of truth when instrumenting the code. If we have both bytecode and FCG
code, we would simply apply these break points twice to either.
Notable changes:
- Removed many functionality from BreakLocation.
- Instrumentation (patching code for breaks) happens by applying break
point info onto code.
- Instrumentation (code patching) is done by the BreakIterator. For
bytecode, it's BytecodeArrayBreakIterator. For FCG code, it's
CodeBreakIterator.
- Changes to code instrumentation mostly involves clearing current
instrumentation and then (re-)applying break points.
- DebugInfo can now reference both bytecode and FCG code.

We used to emit debug break location on block entry. This cannot be
ported to the interpreted as we do not emit bytecode for block entry.
This made no sense to begin with though, but accidentally added
break locations for var declarations.
With this change, the debugger no longer breaks at var declarations
without initialization. This is in accordance with the fact that the
interpreter does not emit bytecode for uninitialized var declarations.
Also fix the bytecode to match full-codegen's behavior wrt return
positions:
- there is a break location before the return statement, with the source
position of the return statement.
- right before the actual return, there is another break location. The
source position points to the end of the function.

Debug-evaluate used to resolve stack variables that shadow
context variables incorrectly, since the stack variable is
not visible in the context chain.
To fix this, we limit local variables accessible by debug-
evaluate to the ones directly referenced inside the function.
What is not referenced by the function itself, is considered
optimized out and not accessible by debug-evaluate.
To achieve this, we duplicate the entire context chain up to
the native context, and write back changes after debug-
evaluate. Changes to the original context chain will however
be overwritten. This already happens for catch and block
scopes though.
Also fix a crash caused by declaring variables inside debug-

Prior to this patch, we enter a global debug mode whenever a break point
is set. By entering this mode, all code is deoptimized and activated
frames are recompiled and redirected to newly compiled debug code.
After this patch, we only deoptimize/redirect for functions we want to
debug. Trigger for this is Debug::EnsureDebugInfo, and having DebugInfo
object attached to the SFI prevents optimization/inlining.
The result is that we can have optimized code for functions without break
points alongside functions that do have break points, which are not
optimized.

(parser or code) and to be explicit about cache consumption or production
(rather than making presence of cached_data imply one or the other.)
Also add a --cache flag to d8, to allow testing the functionality.
-----------------------------
API change
Reason: Currently, V8 supports a 'parser cache' for repeatedly executing the same script. We'd like to add a 2nd mode that would cache code, and would like to let the embedder decide which mode they chose (if any).
Note: Previously, the 'use cached data' property was implied by the presence of the cached data itself. (That is, kNoCompileOptions and source->cached_data != NULL.) That is no longer sufficient, since the presence of data is no longer sufficient to determine /which kind/ of data is present.
Changes from old behaviour:
- If you previously didn't use caching, nothing changes.
Example:
v8::CompileUnbound(isolate, source, kNoCompileOptions);
- If you previously used caching, it worked like this:
- 1st run:
v8::CompileUnbound(isolate, source, kProduceToCache);
Then, source->cached_data would contain the
data-to-be cached. This remains the same, except you
need to tell V8 which type of data you want.
v8::CompileUnbound(isolate, source, kProduceParserCache);
- 2nd run:
v8::CompileUnbound(isolate, source, kNoCompileOptions);
with source->cached_data set to the data you received in
the first run. This will now ignore the cached data, and
you need to explicitly tell V8 to use it:
v8::CompileUnbound(isolate, source, kConsumeParserCache);

Preparsing is always maximally lazy (every function that can be lazy is preparsed
lazily), but Parser has more complicated laziness logic.
If we're going to parse eagerly, and we have preparse data from lazy preparsing,
we're gonna have a bad time. The symbol stream won't contain symbols inside lazy
functions, and when the Parser parses them eagerly, it will consume symbols from
the symbol stream, and everything will go wrong.
This bug was hidden because the symbol cache was not used for real (see
https://codereview.chromium.org/172753002/ ).

Made operator* return reference to the raw type, not pointer. New method 'get()' should be used when raw pointer is needed.
Also removed useless inline modifier from the SmaprtPointer methods and added const modifier to the methods that don't change smart pointer.
Made ~SmartPointerBase protected to avoid accidental calls of the non-virtual base class's destructor.
drive-by: fixed use after free in src/factory.cc

The test in question (test-debug/LiveEditEnabled) is expected to fail, and it
failed, but because of the wrong reason (the test asserts that the default
isolate is not initialized, SetLiveEditEnabled initialized the default
isolate because it doesn't get one as param). Now it fails because of the right
reason.

* AstNode now has a position info.
* Removed various ad-hoc position infos from subclasses (most of which had it).
* Position is always set with the constructor, instead of later.
* Take care to use kNoPosition in the right spots, to not crash the debugger.
Still to do:
* Eliminate Conditional::then/else_position and WhileStatement::condition_position.
* Make CaseClause a proper AstNode and eliminate its custom position.
* If possible, eliminate all uses of kNoPosition.

Drop the previous Mutex and ScopedLock classes from platform files.
Add new Mutex, RecursiveMutex and LockGuard classes, which are
designed after their C++11 counterparts, so that at some point
we can simply drop our custom code and switch to the C++11
classes. We distinguish regular and recursive mutexes, as the
latter don't work well with condition variables, which will be
introduced by a followup CL.

These methods have been superceeded by equivalents accepting object arguments exposing more details.
This is exactly the same change as r15708 which was reverted in r15710 due to pending Blink changes. Now that Blink is rolled to 154493 it should be safe to land this (required Blink change is 154386).
