• ​http://bugs.webkit.org/show_bug.cgi?id=16684 eliminate debugger overhead from function body execution

Speeds SunSpider up 1.003x. That's a small amount, but measurable.

• JavaScriptCore.exp: Updated.
• kjs/Parser.h: (KJS::Parser::parse): Create the node with a static member function named create() instead of using new explicitly.

• kjs/grammar.y: Changed calls to new FunctionBodyNode to use FunctionBodyNode::create().

• kjs/nodes.cpp: (KJS::ProgramNode::create): Added. Calls new. (KJS::EvalNode::create): Ditto. (KJS::FunctionBodyNode::create): Ditto, but creates FunctionBodyNodeWithDebuggerHooks when a debugger is present. (KJS::FunctionBodyNode::execute): Removed debugger hooks. (KJS::FunctionBodyNodeWithDebuggerHooks::FunctionBodyNodeWithDebuggerHooks): Added. (KJS::FunctionBodyNodeWithDebuggerHooks::execute): Calls the debugger, then the code, then the debugger again.

• kjs/nodes.h: Added create functions, made the constructors private and protected.
