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
expression is obsolete by now.

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

Port r10220 (1dae466).

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.
