2f7c192676 Get rid of recursive locks for job based recompilation

0882d3ff81 [turbofan] Initial version of branch cloning. 
This implements a special case of block cloning to recognize constructs like

 if (a ? b : c) { ... }

that happen to be generated by Emscripten quite often.

27e8a455df Rename Interface to ModuleDescriptor 
ModuleDescriptor will end up holding the set of data described in the
spec as a "Module record". This introduces a little bit of confusion
with ModuleInfo, but I hope that'll become clearer over time.

Also removed the interface-printing flags. We probably want
Module-printing flags, but that can wait until we have more
Module-related structures.

acd9c46ca7 [turbofan] Optimize certain chains of Branch into a Switch. 
This adds a new ControlFlowOptimizer that - for now - recognizes chains
of Branches generated by the SwitchBuilder for a subset of javascript
switches into Switch nodes. Those Switch nodes are then lowered to
either table or lookup switches.

Also rename Case to IfValue (and introduce IfDefault) for consistency.

d8cfbc633d [turbofan] Split pure nodes in the scheduler if beneficial. 
If a (pure) node has two or more uses, but there exists a path from the
common dominator of these uses to end, which does not contain a use,
then we split the node such that no unnecessary computation takes place.
Note however, that this only applies if the node cannot be hoisted out
of a loop.

feffccca22 Profiler improvements 
(1) --prof-cpp: Collects ticks like --prof, but ignores code creation events to reduce distortion (so all JS ticks will be "unaccounted"). Useful for profiling C++ code.
(2) --timed-range flag for tick processor: Ignores ticks before the first and after the last call to Date.now(). Useful for focusing on the timed section of a test.
