We already do this for binary-ops, unary-ops and comparisons. Typefeedback for named loads can now also
be in "uninitialized" state which means that the corresponding load IC was never executed.

According to ES5 10.4.2(3), eval calls of strict code always require
their own lexical and variable environment. For now we just add a new
scope when we parse the strict mode directive. The clean solution would
be to always have this sope present (even for global eval calls) and
adapt variable binding to cope with that.

Ensure that generated code for object literals will call Runtime_DefineOrRedefineAccessorProperty only once per accessor property.

To do this, we collect all accessor properties in a first pass and emit code for
defining those properties afterwards in a second pass.

As a finger exercise, the table used for collecting accessors has a (subset of
an) STL-like iterator interface, including STL-like names and operators.
Although C++ is quite verbose here (as usual, but partly this is caused by our
current slightly clumsy classes/templates), things work out quite nicely and it
cleans up some confusion, e.g. a table entry is not an iterator etc.
Everything compiles into very efficient code, e.g. the loop condition 'it !=
accessor_table.end()' compiles into a single 'testl' instruction on ia32.
+1 for using standard APIs!
