Lazily save double registers for HCallRuntime instructions within Hydrogen code stubs.
...
Right now we eagerly save all allocatable double registers upon
entry to every Hydrogen code stub that uses HCallRuntime, and
restore them when we return. Since the HCallRuntime is on the
fallback path for code stubs, this is both a waste of time and
stack space in almost every case.
This patch adds a flag to the HCallRuntime, which controls whether
the instruction saves the double register itself (using the save
doubles flag for the CEntryStub), or whether its up the surrounding
code to handle the clobbering of double registers.

Patch to enhance the source code line information for profiler.
...
This patch is to enhance the source code line information for profiler.
For the Hydrogen compilation, most of the source code line information
is not copied from the HInstruction the to corresponding LInstruction.
This patch defines one PositionBits field for LInstruction and copies the
sorce code position value from the HInstruction.
When Generating the native code, we use RecordPosition(..) function to
write LInstruction's position value to position recorder.
For the MIPS platform, I did not touch because I have no devices
to verify the modification on it.

First implementation of allocation elimination in Hydrogen.
...
This change implements a simple data-flow analysis pass over captured
objects to the existing escape analysis. It tracks the state of values
in the Hydrogen graph through CapturedObject marker instructions that
are used to construct an appropriate translation for the deoptimizer to
be able to materialize these objects again.
This can be considered a combination of scalar replacement of loads and
stores on captured objects and sinking of unused allocations.
