This removes the requirement for handles as arguments, but also removes
concurrency support, which is not being used at the moment.

Supporting concurrency could be done by introducing a sibling class to
IdentityMap that includes RelocationLock on method calls.

    The lack of a vector slot for the keyed store operation in filling in
    non-constant array literal properties led to undesirable contortions in
    compilers downwind of full-codegen. The use of a single slot to initialize all

This patch only treats non-private symbols as valid feedback, thus
avoiding the need to switch to Oddballs for the feedback sentinels
and avoiding breaking the use of private own symbols.

Crankshaft will also optimize these symbol loads into a named load,
just as it does for string keyed loads with type feedback.

    port 5cf1c0bc (r31087).

    original commit message:
    Previous to this patch, both the lithium and TurboFan register
    allocators tracked allocated registers by "indices", rather than
    the register codes used elsewhere in the runtime. This patch
    ensures that codes are used everywhere, and in the process cleans
    up a bunch of redundant code and adds more structure to how the
    set of allocatable registers is defined.

    Some highlights of changes:

    * TurboFan's RegisterConfiguration class moved to V8's top level
      so that it can be shared with Crankshaft.
    * Various "ToAllocationIndex" and related methods removed.
    * Code that can be easily shared between Register classes on
      different platforms is now shared.
    * The list of allocatable registers on each platform is declared
      as a list rather than implicitly via the register index <->
      code mapping.

    additional comment:
    This patch must be work with CL https://codereview.chromium.org/1405673003/
    and CL https://codereview.chromium.org/1413343002/
    which provide the needed register allocation common code change in
    v8 for this CL

   Currently X87 turbofan backend use only one double register. But crankshaft needs to use more than 1
   double register. The reason is that the X87 register is stack-based and the register allocator use
   the same algorithm for all registers. So the backend of X87 needs to maintain the X87 stack status
   between basic blocks during code generation. But for Turbofan backend, it can only handle discrete
   platform-related LIRs. It's difficult to maintain the x87 stack status during different basic blocks.
   So we use the register configuration selection mechanism to return different register configuration
   for X87 turbofan and crankshaft seperately.

   This CL is a follow-up of https://codereview.chromium.org/1405673003/.

Fills out some more of the function prologue support in the
interpreter. Deals with creation of arguments objects and throwing
IllegalRedeclarations if necessary. Also adds (untested) support for
this.function and new.target variable assignment.

Also fixes a bug in Frames::is_java_script() to deal with
interpreter frames correctly.

Cleans up comments in builtins InterpreterEntryTrampoline about
missing prologue support.

Adds the following bytecodes:
  - CreateArgumentsSloppy
  - CreateArgumentsStrict

Unifies the global and unallocated variable type accesses given that
--global_var_shortcuts is going away. Lda/StaGlobal is modified to use
Load/StoreICs on the global object. The named LoadIC and StoreIC bytecodes
are also modified so that they take a constant pool entry index for the
name rather than a register, avoiding unecessary LdaConstant bytecodes to
be emitted.

This slightly generalizes the current mechnanism for property loads to
also deal with property stores (both monomorphic and polymorphic). It's
still somewhat adhoc, but it already handles a lot of the interesting
cases. We might want to wait for keyed accesses before we start
refactoring to a more general solution.
