Anton Afanasyev	e6ea17a9ce	Adds -ftime-trace option to clang that produces Chrome chrome://tracing compatible JSON profiling output dumps. ... This change adds hierarchical "time trace" profiling blocks that can be visualized in Chrome, in a "flame chart" style. Each profiling block can have a "detail" string that for example indicates the file being processed, template name being instantiated, function being optimized etc. This is taken from GitHub PR: https://github.com/aras-p/llvm-project-20170507/pull/2 Patch by Aras Pranckevičius.
