If #2164 was merged, we will have gcc-10 support. GCC 10 will have a good capability to do excellent Link Time Optimization. Besides, we vendor most of our dependencies, which means there may be more room to do the optimization.

Issues found during my local exps:

  1. some warning flags suppression does not take effect in LTO, (maybe-uninitialized), we may disable -Werror or add -Wno-maybe-uninitialized in LTO mode
  2. ODR violation detected due to usage of anon namespace in header file: dbms/src/DataStreams/UnionBlockInputStream.h
