profiler: Reenable built-in profiler
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile when configured with --enable-profiler. Turned out the profiler has been broken for a while. This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode. This also fixes the compile error. This changes profile_getclock() to return nanoseconds rather than CPU ticks as the "profile" HMP command prints seconds and there is no platform-independent way to get ticks-per-second rate. Since TCG is quite slow and get_clock() returns nanoseconds (fine enough), this should not affect precision much. This removes unused qemu_time_start and tlb_flush_time.
