Uses of a value are weighted by a factor of FLAG_loop_weight (default: 10) for
every loop they are in. This makes uses in inner loops "more important", which
should improve the result of the representation inference.

We don't need to store the full representation for each value. Instead
a bit to indicate tagged/untagged is enough.

Reading the virtual register from a LOperand is only needed used for
unallocated LOperands (LUnallocated). There is no need for having a

CheckHelper was only used within the macro itself. Furthermore, GCC
with -Winline was not always happy with the inline function. Simple
solution: Inline the inline function into the macro itself. Inlining
squared!

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.
