7a675e0e3b [x64] Fix instruction selection for Word64Equal(Word64And, 0). 
This fixes a slight inconsistency in the InstructionSelector that
basically disabled the optimization for things like ObjectIsSmi.

c9a49da0d8 [turbofan] Enable deoptimization for non-asm.js TurboFan code. 
Replace the --turbo-deoptimization flag with --turbo-asm-deoptimization
and enable deoptimization for non-asm.js TurboFan code unconditionally.

0a7d4f496a Added %_NewConsString intrinsic. 
No compiler support for now (BTW: %_NewString, doesn't have that,
either), inline allocation will come later. Hopefully the last
intrisic to add for a StringAddStub POC...

20dce719ee Added %_HeapObjectGetMap and %_MapGetInstanceType intrinsics. 
These are needed (among other things) for a TurboFan-generated
StringAddStub. Furthermore, they can be used to nuke the overly
complex %_IsInstanceType intrisic, it's completely expressible in
JavaScript now, but that will be done in a separate CL.

Alpha-sorted things a bit on the way to ease navigation.

4f1597a92d [turbofan] Add new JSIntrinsicsLowering reducer. 
The lowering of intrinsics is therefore now decoupled from the general
inlining logic.

bc475b4a6b Add inlining for intrinsics. 
This issue is for discussion on how to proceed.

I think the implementation of ValueOf shows that directly creating the IR does not scale.
