Wesley Wiser f5f86be1d4 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.
