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 fixing up pointers on the main thread
- 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
This reverts commit 6df04b296b.

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.

Tests for
* aborting a full page.
* partially aborting a page.
* partially aborting a page with pointers between aborted pages.
* partially aborting a page with store buffer entries.
Also introduces force_oom() which prohibits a old space to
expand

Also introduces ShouldForceOOM() which prohibits a PagedSpace from expanding.
Compaction spaces refer to the corresponding actual space.
