Auto merge of #52212 - kennytm:o3-again, r=alexcrichton
Set opt-level = 3 the third time. This PR reverts #51165 (set -O2 for fixing #50867), which reverted #50329 (set -O3), which was second attempt of #48204 (set -O3, closed due to Windows segfault that is fixed now), which reverted #42123 (set -O2 to fix spurious Windows segfaults), which reverted #41967 (set -O3). Since we have found the root cause of #50867, this optimization could be tried again. Last time we've found that setting -O3 regressed the wall time of NLL (https://github.com/rust-lang/rust/pull/50329#issuecomment-388084894), so we may need another perf run to confirm. I'd like to check this *after* the LLVM 7 upgrade #51966 has been merged, so marking this as <kbd>S-blocked</kbd> for now.
