Split the monster methods in JSNativeContextSpecialization into smaller ones, adding appropriate helpers. Improve the condition checking for strings and numbers using CheckString/CheckNumber when applicable. Also try to merge compatible PropertyAccessInfos, to avoid running into the polymorphic case whenever possible. Drive-by-fix: Don't try to resurrect dead nodes during LoadElimination. With the improve code generation for monomorphic loads, we seem to trigger the dead node resurrection.

perf-turbo.py merges a perf data file and a turbofan trace file into a single json object which can then be piped to a file and uploaded to turbolizer to display the profiling data in the disassembly. With the changes, turbolizer now shows the event counts for instruction in percentage form and with heatmap-stype colouring. Multiple different events can be recorded at once with a new drop-down menu to select which event to view the counts of. The documentation has been updated with instructions. Using the script is optional and turbolizer retains previous functionality if a trace without profiling data is uploaded.

port ba092fb0 (r37971) original commit message: So far we don't have a useful way to inline Math.max or Math.min in TurboFan optimized code. This adds new operators NumberMax and NumberMin and changes the Float64Max/Float64Min operators to have JavaScript semantics instead of the C++ semantics that it had previously. This also removes support for recognizing the tenary case in the CommonOperatorReducer, since that doesn't seem to have any positive impact (and actually doesn't show up in regular JavaScript, where people use Math.max/Math.min instead). BUG= Drive-by-fix: Also nuke the unused Float32Max/Float32Min operators. Review-Url: https://codereview.chromium.org/2187463005 Cr-Commit-Position: refs/heads/master@{#38119}

This adds the build target inspector_protocol_parser_test, which depends on several more inspector protocol related targets. The resulting gtest executable runs, but has failures that have to be fixed. GN build configuration will follow. A copy of v8-inspector/js_protocol.json has been included to be able to use it before the actual migration.

This patch updates internal data structures used by V8 to support multiple indirect function tables (WebAssembly/design#682). But, since this feature is post-MVP, the functionality is not directly exposed and parsing/generation of WebAssembly is left unchanged. Nevertheless, it is being used in an experiment to implement fine-grained control flow integrity based on C/C++ types.
