Make the JSImmediate interface private.

All manipulation of JS values should be through the JSValuePtr class, not by using JSImmediate
directly. The key missing methods on JSValuePtr are:

  • isCell() - check for values that are JSCell*s, and as such where asCell() may be used.
  • isInt32Fast() getInt32Fast() - fast check/access for integer immediates.
  • isUInt32Fast() getUInt32Fast() - ditto for unsigned integer immediates.

The JIT is allowed full access to JSImmediate, since it needs to be able to directly
manipulate JSValuePtrs. The Interpreter is provided access to perform operations directly
on JSValuePtrs through the new JSFastMath interface.

No performance impact.
