3d58b82add Fix for 435073: CHECK failure in CHECK(p->IsSmi()) failed.
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.

d703e87531 Reserve code range block for evacuation.
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

fbcfce69aa Conditional flags for tests - set JS stack size for simulators.
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.
