Reviewed by Oliver Hunt.

* bytecompiler/BytecodeGenerator.cpp:
(JSC::BytecodeGenerator::emitCall): Renamed callFrame to registerOffset
because this value doesn't give you the offset of the callee's call frame.

(JSC::BytecodeGenerator::emitReturn): Tightened to use equality instead
of greater-than. Removed comment since its reasoning was wrong.
        
(JSC::BytecodeGenerator::emitConstruct): Updated for rename mentioned above.

(JSC::BytecodeGenerator::isArgumentNumber): Provided a more precise way
to ask this question, giving the bytecode generator more freedom to change
internal implementation details.
        
* bytecompiler/BytecodeGenerator.h: Reduced default vector capacity because
16 was overkill.
(JSC::CallArguments::registerOffset): Updated for rename mentioned above.

* bytecompiler/NodesCodegen.cpp:
(JSC::CallArguments::CallArguments):
(JSC::CallArguments::newArgument): Factored out argument allocation into
a helper function, so I can change it later.

(JSC::CallFunctionCallDotNode::emitBytecode):
(JSC::FunctionBodyNode::emitBytecode): Use helper function mentioned above.
