• streamline exception handling code for a >1% speed-up of SunSpider

• kjs/nodes.cpp: Changed macros to use functions for everything that's not part of normal execution. We'll take function call overhead when propagating an exception or out of memory. (KJS::createOutOfMemoryCompletion): Added. (KJS::substitute): Use append instead of the relatively inefficient + operator. (KJS::Node::rethrowException): Added.
• kjs/nodes.h: Added rethrowException.
