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.

e4c6f9488e Implement graph trimming in ControlReducer. 
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.

This CL is one half of the ControlReducer functionality, the other half
being branch folding.

496697df4e Add MachineSignature, which is an encapsulation of the machine types for parameters and return values in a graph. 
This utility will be used to simplify Linkage and fix representation inference
to work with graphs where parameters and return values are something other
than tagged. It will also make testing representation inference a lot
easier, since we can then exactly nail down the machine types of parameters
and returns.

This CL also adds c-signature.h, which demonstrates how to convert C function
signatures into MachineSignatures. The CSignatures will be used in tests to
make it easier and simpler to codegen tests.

9523e0acf4 re-land: Track history of events in GCTracer. 
- track incremental marking stats directly on GCTracer.
- add simple ring buffer class.
- track last 10 scavenges and mark-compacts in ring buffers on GCTracer.
- various clean-ups.

This is a re-land of https://codereview.chromium.org/391413006/ with
 - int instead of size_t in ring buffer unit test.
 - git cl format

a0f6878a06 Add mips64 port. 
Summary:

- Changes in common code are mainly boilerplate changes,
gyp and test status files updates.

- On mips64 simulator all tests pass from all test units.

- Current issues: mjsunit JS debugger tests fail randomly on HW in release mode.
Corresponding tests are skipped on HW.

- Skipped tests on mips64: test-heap/ReleaseOverReservedPages, mjsunit/debug-*

ca16bb7ae2 Split out libplatform into a separate libary 
Also remove the "use default platform" compile flag. Instead, the embedder
has to provide the platform.

Change all binaries to use the default platfrom from libplatform.

Unless --job-based-sweeping is passed, nothing uses the platform yet, so
nothing will break for embedders (yet).
