The bug was an error when copying arrays in crankshaft. If it's a holey smi
array, the copy must be done as FAST_HOLEY_ELEMENTS to prevent representation
changes from being inserted that deopt on encountering the hole.
Also, prevent inlining array pop() and shift() if the length is read-only.

If we run out of code range, then GC wouldn't be able to compact code space,
because it wouldn't be able to allocate a new page. This can cause code space
fragmentation and OOM crashes.

- Use "leal" for subtraction of integer constant when non-constant input to
subtract is used more than once.
- Use "incl", "decl", and "addl" when they are smaller/cheaper than their
leal/addl/subl equivalant.

JavaScript shifts perform an implicit '& 0x1F' on their right operand, this
patch removes it when the underlying architecture already does it.

There are separated JS and C stacks on simulators so for some stack
extensive tests (like mozilla/js1_5/extensions/regress-355497) might
cause a C stack overflow and that overflow is not caught by V8. It is
not an issue on real HW. Increasing the C stack also solves the problem
but we have already FLAG_sim_stack_size flag to control the JS stack
size.
This patch makes it possible to add flags to tests conditionally in
.status files.

Since checking all possible combinations is taking so long this
reduces the test to test the odd cases (let, yield and static) as
well as a single ordinary case.

This fixes following exception in Sky on attempt to set a breakpoint
"Unhandled: Uncaught ReferenceError: break_point is not defined"
I think this happens in Sky but not in Chrome because Sky scripts are executed in strict mode.
