Last attempt failed because of too agressive growing and no proper GC
scheduling.
Also refactor live object iteration on the way to avoid a branch when we
know that we will succeed.

This patch also fixes several cctests that require manual GC.

Most callers passed kFinalizeIncrementalMarkingMask, so use that as
a default argument (not using default argument syntax to avoid including
heap.h in cctest.h).

Now callers of Heap::CollectGarbage* functions need to
specify the reason as an enum value instead of a string.
Subsequent CL will add stats counter for GC reason.

Rebuilding (after touching certain files) is crazy slow because
includes are out of control. Many of these files we need to rebuild are
cctests which pull in more includes than they need.

- Move usable functions into proper heap-utils.h/.cc files and remove
utils-inl.h file
- Fix assumptions accross the board relying on certain behavior that is not
invariant
This is a requirement for modifying page size.

- Get rid of sweeping on the main thread
Instead:
- Record (and process afterwards) slots in parallel
- Add the pages to the concurrent sweeper as pointers have already been fixed

Before this CL, free memory (FreeSpace) has been managed through a global free
list that contains single-linked lists of FreeSpace nodes for each size class.
We move away from this approach to a global two-level doubly-linked list that
refers to singly-linked lists of FreeSpace nodes on the corresponding pages.
This way we can refill on a page-level granularity. Furthermore, it also enables
constant-time eviction of pages from the free list.
