Here at Fuchsia we would eventually like to switch to the new PM by
default. We have slowly been porting relevant passes from the legacy PM.
AFAIK there hasn't been a dedicated timeline, but one of our goals is to
get an upstream new PM buildbot running.
We were going to make a bot once all tests pass when the new PM is enabled
by default. I've been addressing these tests over the past couple of weeks.
Currently there are only 4 tests that fail under new PM and are being
addressed in https://reviews.llvm.org/D63174. Ideally when this is
committed (and assuming no other tests fail), we can get an upstream bot.
