6c0a4f5d45 Fix bug with filtering of foreign context maps in the type feedback. 
The first attempt did not properly handle keyed loads/stores and
did not check the constructors of the objects in the prototype
chain.

Added two more tests to handle the fixed cases.

This just simplifies the command line used to run test cases, allowing
to copy them from the test harness output without editing. The passed

502039a6bd Fix invalid usage of StoreIC_ArrayLength optimization. 
This introduces an additional check into the StoreIC_ArrayLength builtin
checking that the array still has fast properties. Redifinitions of the
length property that would cause it's type or attributes to change, will
switch to slow properties, thereby invalidating said optimization.

This test deleted its working directory and then tried to run several
shell commands which caused a failure on nfs.

Changes:
-TEST_DIR is only removed at the very end of the test
-the working directory is changed to /tmp at the beginning so that
 every iteration (when running with --stress-opt) has a valid working directory

Original commit message:

This CL adds support for loading from and storing to context slots
belonging to harmony let or const bound variables. Checks for the
hole value are performed and the function is deoptimized if they fail.
The full-codegen generated code will take care of properly throwing
a reference error in these cases.

1028cf2631 Optimize the equality check case of ICCompare stubs. 
This includes specialcasing the generation when we know that the maps
of the two objects are the same. In addition, a new specialized
compare ic known objects cache is created.

The reason for the cache is that we need to have access to the stub
code from the roots; if we do not, the GC will collect the stub. In
this specialized case we use the map pointer as key in the cache, and
we always do a lookup before generating code. Actually hitting
something in the cache will happen very rarely, but we could
potentially overwrite an existing stub, which again will lead to the
GC collecting this old stub (even if it is referenced from other code
objects)

a457040ca6 Ensure that non-optimized code objects are not flushed for inlined functions. 
Collector was flushing them if optimized code was reachable only through the stack (not through the JSFunction object) which happens when you have a pending lazy deoptimization.

Also prevent v8::Script::New from leaking internal objects allocated by the compiler into outer HandleScope.
