• ​http://bugzilla.opendarwin.org/show_bug.cgi?id=4124 (change JavaScript property access to avoid double lookup)

• 10% speedup on JavaScript iBench
• 5% speedup on 24fun BenchJS benchmark

Changed all get methods to getOwnProperty - they are no longer
responsible for prototype lookup, and determine if the property
was found as a side efect.

get() is now a nonvirtual ObjectImp method which calls the virtual
getOwnProperty and walks the prototype chain. A few selected
methods were inlined.

Changed ResolveNode::evaluate plus some other places to use
getProperty which does get() and hasProperty() in one lookup.

Also miscellaneous code cleanup.
