This change introduces adjustPassManager target callback giving a target an opportunity to tweak PassManagerBuilder before pass managers are populated.

This generalizes and replaces addEarlyAsPossiblePasses target callback. In particular that can be used to add custom passes to extension points other than EP_EarlyAsPossible.

If approved the similar change to clang's BackendUtil.cpp will be created.
