Reviewed by Sam "That doesn't look like what I thought it looks like" Weinig.

Beefed up the JSValuePtr class and removed some non-JSValuePtr dependencies
on JSImmediate, in prepapration for making JSImmediate an implementation
detail of JSValuePtr.

SunSpider reports no change.

• interpreter/Interpreter.cpp: (JSC::Interpreter::privateExecute):
• jit/JIT.cpp: (JSC::JIT::privateCompileMainPass):
• jit/JITArithmetic.cpp: (JSC::JIT::compileFastArith_op_mod):
• runtime/JSGlobalObjectFunctions.cpp: (JSC::globalFuncParseInt): Updated for interface changes.

• runtime/JSImmediate.h: (JSC::JSValuePtr::JSValuePtr):
• runtime/JSValue.h: (JSC::JSValuePtr::): (JSC::jsImpossibleValue): (JSC::jsNull): (JSC::jsUndefined): (JSC::jsBoolean): (JSC::JSValuePtr::encode): (JSC::JSValuePtr::decode): (JSC::JSValuePtr::JSValuePtr): (JSC::JSValuePtr::operator bool): (JSC::JSValuePtr::operator==): (JSC::JSValuePtr::operator!=): (JSC::JSValuePtr::isUndefined): (JSC::JSValuePtr::isNull): Changed jsImpossibleValue(), jsNull(), jsUndefined(), and jsBoolean() to operate in terms of JSValuePtr instead of JSImmediate.
