ca3abde2fa [turbofan] Variable liveness analysis for deopt. 
This change introduces a liveness analyzer for local variables in frame states.

The main idea is to use the AstGraphBuilder::Environment class to build the control flow graph, and record local variable loads, stores and checkpoints in the CFG basic blocks (LivenessAnalyzerBlock class).

After the graph building finishes, we run a simple data flow analysis over the CFG to figure out liveness of each local variable at each checkpoint. Finally, we run a pass over all the checkpoints and replace dead local variables in the frame states with the 'undefined' value.

eacd6d8b7d [turbofan] Make inlining independent of typing. 
The JSInliner used to load the context from the JSFunction node at
runtime, which introduced a HeapConstant (because we had to materialize
the JSFunction after context specialization) and a LoadField operation,
independent whether the inlinee actually uses the context. This is
rather cumbersome currently, and therefore this is now changed to just
embed the context constant instead. Once we do inlining based on
SharedFunctionInfo rather than JSFunction, we should reconsider this
decision and come up with a proper heuristic.

25895aeeaf [turbofan] Add support for inlining of builtins. 
We mark certain builtins for inlining, and those should always be
inlined into optimized code (CrankShaft already handles it this way), so
we should support that in TurboFan as well. Currently this mainly
affects a certain set of Math functions, but once have the basics in
place we can extend this to any kind of builtin/code stub/accessor.

This adds a new flag --turbo_builtin_inlining (enabled by default), that
forces the inliner to always inline builtins marked for inlining, but
does not affect inlining of other functions (this is still controlled by
the --turbo-inlining flag).

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.

0b9a70ade3 Remove --harmony implications for incomplete features 
This is in preparation for making --harmony and --es-staging synonyms.
The only remaining difference currently is block-scoping, which is still
implied by --harmony, to avoid regressing on a long-available feature.

Also removes the special-casing of --harmony-proxies.

90a7f07489 Implement loop variable assignment analysis. 
This analysis computes the set of variables that are assigned in each loop. This is useful to avoid creating redundant loop phis when building an SSA graph, which just waste memory and require analysis to get rid of.

This CL implements an AST walk for the analysis and plugs the result into the TurboFan graph builder. I left this analysis under a flag for A/B testing and until sufficient unit tests can be developed.

Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures
such as Promise make use of symbolToStringTag (as they are supposed to, see v8:3241), and changes further once
Symbol.toStringTag is exposed publicly.

566cdc3bcd Reland "Add initial support for inlining." 
Reland Fixes:
* Remove usage of C++11 vector members.
* Guard tests by V8_TURBO_TARGET.

Changes:
* Make context specialization clean up after itself.
* Add UpdateToAndIncrement to Inputs::iterator.
  Uses:iterator already provides this member function.
* Allow next node id in graph to be set.

6d3fc8a322 Introduce FLAG_vector_ics. 
When FLAG_vector_ics is true, then AST nodes that use Load and KeyedLoad ICs
will allocate a type vector slot to store feedback information. Full codegen
will emit a load of the slot into a register if the flag is on.

Support is incomplete, right now the IC doesn't know how to use the feedback
slot.
