be8e8f7528 Improve the JitCodeEventHandler API to add support for line position information. 
This includes:

* adding the CODE_ADD_LINE_POS_INFO, CODE_START_LINE_INFO_RECORDING, CODE_END_LINE_INFO_RECORDING event and the corresponding functionality.
 * adding the JITCodeLineInfo struct to record the code line info. I added this definition because Danno mentioned that "we'd like to cleanup and decouple the external debugging functionality"
 * some other small changes.

250ebdc2be ARM: Change signature for vmov.32 function in the assembler 
The assembler has 8 different vmov variants. The one for vmov.32 and for moving
an immediate into a double reg only differs in the type of the second
paremeter: vmov.32 takes an int, the other takes a double.

The situation is dangerous because C++ will happily implicitly convert between
int and double.

This patch changes the signature of the vmov.32 assembler function so that it
cannot be confused with the other vmovs.

05e95eee0e Allow full inlining of f.apply(this, arguments) calls. 
This allows Crankshaft to completely inline a f.apply() dispatch if the
exact number of arguments is known and the function is constant. The
deoptimizer doesn't generate the f.apply() frame during deoptimization,
so the materialized frames look like f.apply() did a tailcall.

eb573e1122 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.

5aafde9285 Print deoptimization index when printing lithium environment. 
Output of --trace-deopt --code-comments does not always allow to reliably match deoptimization to the lithium instruction (and it is actually never accurate on x64 due to one level of indirection). This change allows to reliably figure out which instruction deoptimized just by looking up bailout id in the hydrogen.cfg.
