Michael Anthony Knyszek 4c943abb95 runtime: fix comments on the behavior of SetGCPercent ... Fixes for #49680, #49695, #45867, and #49370 all assumed that SetGCPercent(-1) doesn't block until the GC's mark phase is done, but it actually does. The cause of 3 of those 4 failures comes from the fact that at the beginning of the sweep phase, the GC does try to preempt every P once, and this may run concurrently with test code. In the fourth case, the issue was likely that only *one* of the debug_test.go tests was missing a call to SetGCPercent(-1). Just to be safe, leave a TODO there for now to remove the extraneous runtime.GC calls, but leave the calls in. Updates #49680, #49695, #45867, and #49370.
