1. heap-inl.h has a function Heap::_inline_get_heap_ that calls
Isolate::Current() defined in isolate.h, so heap-inl.h requires
isolate.h.

2. Isolate has an embedded Heap member, so isolate.h requires heap.h.

3. heap.h has inline functions functions defined that call
Heap::_inline_get_heap_, so heap.h requires heap-inl.h (!).

The upshot is that all three need to be included wherever one is.  A
simpler way is to break the cycle by moving the inlined functions in
heap.h to heap-inl.h.

The detailed heap snapshot has two groups of nodes. The first one
is the group for v8 heap nodes and the second one is the group for
native objects. At the moment we have two different sets of native
objects. There are 'Detached DOM trees' and 'Document DOM trees' type of objects.

I think it'd be nice to replace one group containing all native objects with
separate groups for different types of native objects.

On MIPS we cannot double the number of deoptimization entries easily
because the generated code would contain long branches (>128K) and we use
BlockTrampolinePoolScope in the Deoptimizer::TableEntryGenerator::GeneratePrologue method.
Also, we cannot use the Jr instruction here because the Deoptimizer::CreateCode method asserts
that the generated code does not contain reloc information.

This simple refactoring makes it very clear that clearing non-live transitions
actually consists of 2 quite separate things. Things would even be nicer if the
prototype transitions were represented by a separate data structure instead of
reusing FixedArray in an interesting way once again.

As an additional bonus, this CL makes it possible to read each of the methods in
question on a 30" screen without scrolling!

This changes the heuristics for the high promotion mode to be checked
on all GCs (including scavenges), so that changes in the applications
behavior are recognized earlier. It also fixes miscalculations in the
survival counter and rate which caused heuristics to fail completely.
