CL 36428 changed the way nanotime works so on Darwin and Windows it now depends on runtime.startNano, which is computed at runtime.init time. Unfortunately, the `runtimeInitTime = nanotime()` initialization happened *before* runtime.init, so on these platforms runtimeInitTime is set incorrectly. The one (and only) consequence of this is that the start time printed in gctrace lines is bogus: gc 1 18446653480.186s 0%: 0.092+0.47+0.038 ms clock, 0.37+0.15/0.81/1.8+0.15 ms cpu, 4->4->1 MB, 5 MB goal, 8 P To fix this, this commit moves the runtimeInitTime initialization to shortly after runtime.init, at which point nanotime is safe to use. This also requires changing the condition in newproc1 that currently uses runtimeInitTime != 0 simply to detect whether or not the main M has started. Since runtimeInitTime could genuinely be 0 now, this introduces a separate flag to newproc1. Fixes #21554.
