MIPS: Generate the TransitionElementsStub using Crankshaft
Port r13585 (
4174b9d2)
Original commit message:
This includes:
* Adding support for saving callee-clobbered double registers in Crankshaft code.
* Adding a new "HTrapAllocationMemento" hydrogen instruction to handle AllocationSiteInfo data in crankshafted stubs.
* Adding a new "HAllocate" hydrogen instruction that can allocate raw memory from the GC in crankshafted code.
* Support for manipulation of the hole in HChange instructions for Crankshafted stubs.
* Utility routines to manually build loops and if statements containing hydrogen code.

Better fix for MemoryChunk::owner().
Pointer arithmetic such as "owner_ - kFailureTag" is undefined behaviour
unless owner_ points to a valid object.
This allowed Clang to assume the subtraction would never be NULL,
causing problems in the caller (see https://codereview.chromium.org/

To fix this, we should cast owner_ to intptr_t before doing the

Only mark the descriptor that is valid for the map in question. If this map
transitioned from a map with a different descriptor array (or has no back
pointer), mark all valid descriptors from the start.
This fixes the following memory leak: Map A shares a descriptor array
with map B. Map B adds constant function c that in its scope holds on to
an instance of B. If the descriptor array of A would keep all the shared
descriptors alive, including c, this keeps alive both A and c
indefinitely.
This CL also fixes a bug in descriptor array trimming. When trimming
descriptor arrays we need to trim off the slack as well (thus the entire
storage); and since we are trimming a descriptor array, we need to trim
* kDescriptorSize.

profiler: log solib addresses unconditionally
Make --prof_lazy log the addresses of shared libraries. Without those addresses,
the output of the tick processor is not very useful for node.js applications.
Address logging was disabled for --prof-lazy in r3154 for reasons that no longer
apply: the profiler is started on demand and hence looking up the addresses is
deferred until it's actually necessary.
