Change Details

Some targets may add required passes via TargetMachine::registerPassBuilderCallbacks(). We need to run those even under -O0. As an example, BPFTargetMachine adds BPFAbstractMemberAccessPass, a required pass. Tests are a continuation of those added in https://reviews.llvm.org/D89083.

Some targets may add required passes via TargetMachine::registerPipelineStartEPCallback(). We need to run those even under -O0. As an example, BPFTargetMachine adds BPFAbstractMemberAccessPass, a required pass. The legacy PM adds EP_EarlyAsPossible and EP_EnabledOnOptLevel0 for -O0. We match EP_EarlyAsPossible here. Currently EP_EnabledOnOptLevel0 is only used for coroutine and sanitizer passes, which can be manually added (as is currently done). (This can be revised in the future if deemed necessary) Tests are a continuation of those added in https://reviews.llvm.org/D89083.
