82d1f51534 Give uses within a loop a greater weight when doing representation inference.
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.

b2ead52688 Save zone memory in LEnvironment by using a bit vector.
We don't need to store the full representation for each value. Instead
a bit to indicate tagged/untagged is enough.

87ccb1d740 Break a circular include dependency.
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.

07d720ec41 Detailed heap snapshot usability improvement.
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.

0d4fc913d0 MIPS: Reverted the number of deopt entries to 4096.
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.

448b6bbc41 Flush number string cache on GC (bug 1605). Also start with a small
number string cache and only grow it if needed, which will be useful
for saving boot time memory use.
This is a second try for  https://chromiumcodereview.appspot.com/923502
after fixing an unrelated stack overflow issue.
