b7b2fd4cec Implement a hash based look-up to speed up containing address check in large
object space. Before, it was a link-list based look-up, and make this function
a little bit 'hot' from profile point.

an optimized frame spill slot may be mistakenly seen as a marker value.

It also breaks the debugger reproducably: Tested when enabling alignment

79a98de9f7 Fix declarations escaping global strict eval.
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.

c644c4e811 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!

7d6fd56fd5 Ensure there is a smi check of the receiver for global load and call ICs.
There was a comment that, for such ICs specialized to the global object,
they were always contextual loads.  This is very brittle.  It is a
micro-optimization that relies too much on the way that things happen to
work today.

Instead, never omit the smi check because it's safer.
