[NewPM] Support optnone under new pass manager OptNoneInstrumentation is part of StandardInstrumentations. It skips functions (or loops) that are marked optnone. The feature of skipping optional passes for optnone functions under NPM is gated on a -enable-npm-optnone flag. Currently it is by default false. That is because we still need to mark all required passes to be required. Otherwise optnone functions will start having incorrect semantics. After that is done in following changes, we can remove the flag and always enable this. Reviewed By: ychen Differential Revision: https://reviews.llvm.org/D83519

Disable most IR-level transform passes on functions marked 'optnone'. Ideally only those transform passes that run at -O0 remain enabled, in reality we get as close as we reasonably can. Passes are responsible for disabling themselves, it's not the job of the pass manager to do it for them. llvm-svn: 200892
