Add support for enabling the LLVM time-trace feature
I found this helpful while investigating an LLVM performance issue. Passing `-Z llvm-time-trace` causes a `llvm_timings.json` file to be created. This file can be inspected in either the Chrome Profiler tools or with any other compatible tool like SpeedScope. More information on the LLVM feature: - https://aras-p.info/blog/2019/01/16/time-trace-timeline-flame-chart-profiler-for-Clang/ - https://reviews.llvm.org/rL357340
