Bug 1370329 (part 1) - Clean up the profiler's RAII classes. r=mstange.

This patch does the following renamings, which increase consistency.

- GeckoProfilerInitRAII -> AutoProfilerInit
- GeckoProfilerThread{Sleep,Wake}RAII -> AutoProfilerThread{Sleep,Wake}
- GeckoProfilerTracingRAII -> AutoProfilerTracing
- AutoProfilerRegister -> AutoProfilerRegisterThread
- ProfilerStackFrameRAII -> AutoProfilerLabel
- nsJSUtils::mProfilerRAII -> nsJSUtils::mAutoProfilerLabel

Plus a few other minor ones (e.g. local variables).

The patch also add MOZ_GUARD_OBJECT macros to all the profiler RAII classes
that lack them, and does some minor whitespace reformatting.
