Simplify behavior of code stubs that accept a variable number of stack
arguments in addition to their parameters. Before, we'd add a special
variable to the environment with the value of a register with the
number of arguments. Now, that register just appears as a parameter to
the code stub.

Provide private symbols through internal APIs

Adds a notion of private symbols, mainly intended for internal use, especially, self-hosting of built-in types that would otherwise require new C++ classes.

On the JS side (i.e., in built-ins), private properties can be created and accessed through a set of macros:

  NEW_PRIVATE(print_name)
  HAS_PRIVATE(obj, sym)
  GET_PRIVATE(obj, sym)
  SET_PRIVATE(obj, sym, val)
  DELETE_PRIVATE(obj, sym)

In the V8 API, they are accessible via a new class Private, and respective HasPrivate/Get/Private/SetPrivate/DeletePrivate methods on calss Object.

These APIs are designed and restricted such that their implementation can later be replaced by whatever ES7+ will officially provide.

Change table size for trigonometric functions.

Sunspider verifies floating point results to the last bit, so this is to
make sure that we return the expected result.

Make HForceRepresentation an idef.

An optimization in the array constructor wasn't firing because the code
would check for constant values, failing to find them through
intervening HForceRepresentation instructions. Repaired this site. A
follow-on CL will provide a better way of making decisions based on
constant HValues.
