Bug 1696422 - Store Firefox symbols dumped while profiling a mochitest in dist/crashreporter-symbols so that they are found during following runs, r=gregtatum.

Details | Review

When I profile a mochitest using ./mach test <mochitestpath> --profiler, I always see "profiler INFO Symbolicating the performance profile... This could take a couple of minutes." taking a while, with the terminal title indicating that we spend a lot of time in dump_syms_mac.

I think we are dumping all symbols every time, and could speed this up with a cache.
