34363bf5aa Introduce a flag to change the new space growth factor 
A useful value would be 4, so we get 1, 4, 16MB (instead of the default
value 2 which leads to 1, 2, 4, 8, 16)

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
fragmentation and OOM crashes.

According to ES5 9.5 and 9.6, NaN, -inf, +inf, -0 and 0 all truncate to
zero for both ToInt32 and ToUint32, so we can be a lot smarter in the
typer, loosing less information upon truncation (i.e. x | 0 and x >>> 0).
