• Remove SymbolTable from FunctionBodyNode and move it to CodeBlock

It's not needed for functions that have never been executed, so no
need to waste the memory. Saves ~4M on membuster after 30 pages.

• VM/Machine.cpp: (JSC::Machine::retrieveArguments):
• parser/Nodes.cpp: (JSC::EvalNode::generateCode): (JSC::FunctionBodyNode::generateCode):
• parser/Nodes.h:
• runtime/JSActivation.h: (JSC::JSActivation::JSActivationData::JSActivationData):
