Fix bug in X64 RegExpExec stub.

Used incorrect register for referencing RegExp data, so it always failed

Fix Issue 1234.
...
Ensure that there is always enough bytes between consequtive calls in
unoptimized code to write a call instruction at the return points
without overlapping.
This handles the case where two return points were only four bytes
apart (because the latter call was to a register).

Refactor polymorphic load and inline function graph construction.

Change the way we construct the graph for polymorphic loads to match that of
polymorphic stores.
Introduce a stack-allocated helper for saving and restoring all the
function-specific graph builder state that needs to change when we begin
translating an inlined function. Make this class authoritative by moving
redundant state out of the builder and deferring to the current function's
state.
Ensure that we always print a tracing message when abandoning an inlining
attempt.

Stop using plain Arrays internally in built-in functions.
...
In built-in code we use arrays for internal computations.
This makes it possible to affect the built-in code by putting getters
or setters on the Array prototype chain.
This adds a new internal Array constructor that creates Arrays with
a very simplistic prototype chain that doesn't include any publicly
visible objects. These Arrays shoudl ofcourse never leak outside the
builtins, since that would expose the prototype object.
The prototype object contains only the array functions that we use:
push, pop and join (and not even a toString, so it doesn't stringify
well).
Also change uses of .call to %_CallFunction.

SetElement can cause an exception to be thrown. If its return value

In some cases, it's a matter of returning Exception::Failure() from

In other cases, code using SetElement on a JSArray has been changed
to setting directly on a FixedArray and only creating the JSArray
at the end.

Do not use subgraphs to implement the translation of simple branching

Combine all the loop construction functions into a single one.
Resolve a possible problem with duplicate AST IDs used both for joined loop
break blocks, the normal loop exit, and for their common successor, by never
introducing the extra (successor) block and instead making the normal loop
exit a predecessor of the break join block. There is a similar issue with
joined continue blocks.
Remove a (never needed) two-element zone list per each time we replace one
hydrogen value with another.

I think this actually turns the code in question into dead code, because the current definition of UseSparseVariant only allows arrays in DictionaryMode, and these never return encoded ranges from %GetArrayKeys. This is a subtle link between the definition of %GetArrayKeys and UseSparseVariant, so I would prefer to keep the code rather than having an invisible depeendency.

X64: Implement DoComputeOsrOutputFrame and fix Generate_OnStackReplacement.
...
The existing version does not have a correct implementation of
Generate_OnStackReplacement since we do not correctly find the loop
depth. This is mainly because EmitStackCheck in full-codegen-x64.cc
did not write it and partly due to us reading at the wrong offset
(which had no effect when it was not written in the first place, we
simply got a random number from the next instruction).
The DoComputeOsrOoutputFrame is very similar to the ia32 version.

Fix CPU profiling for Crankshaft.
...
The main issue was due to multiple recompilations of functions. Now
code objects are grouped by function using SFI object address.
JSFunction objects are no longer tracked, instead we track SFI object
moves. To pick a correct code version, we now sample return addresses
instead of JSFunction addresses.
tools/{linux|mac|windows}-tickprocessor scripts differentiate
between code optimization states for the same function
(using * and ~ prefixes introduced earlier).
DevTools CPU profiler treats all variants of function code as
a single function.
ll_prof treats each optimized variant as a separate entry, because
it can disassemble each one of them.
tickprocessor.py not updated -- it is deprecated and will be removed.

Add more generic version of reloc info padding to ensure enough space for reloc patching during deoptimization (fixes issue 1174).
...
The old version only added extra space when we did indirect calls, but
the problem remains the same with normal calls that can be represented
as a single byte. When doing patching each call will always be at
least 2 bytes long because we use RUNTIME_ENTY as the reloc mode.

X64: Refactor the string add in the type recording binary operation stub
...
This makes the code have the same structore as on IA32 and ARM, and will also support possible fast adding a smi and string where the string is to the right and fast adding of String objects.

Fix bug with input representation of HValueOf.
...
The class did not correctly implement the RequiredInputRepresentation.
I changed this functions to be abstract so that all hydrogen classes
must implement it.
As a convention instructions with zero input operands return None as input
representation.
Instructions that can handle all input representations without converting before
also have None as required input representation (e.g. HTest)
All other instructions need a proper required input representation.

Partial refactoring of subgraphs.
...
Change the interface to the Hydrogen graph builder to appear like it
directly holds a current basic block and a current environment.
Remove some direct accesses to the current subgraph, and remove
subgraph accessors that simply forwarded to the exit block.

ARM: Add support for just one string argument in the string add stub
...
Having a string add stub which can handle a string in just one of the arguments is essencial for the type recording binary operation stub when expecting strings. Otherwise string added with e.g. smi will always call the runtime for a type transition which will be back to the same types as the transition code keeps it in string arguments when one argument is a string.
This fixes the regression (especially Delta Blue) caused by replacing the generic binary operation stub with the type recording binary operation stub in the ARM lithium code generator.
