  -----------
  [ASan] Shared optimized callbacks implementation.

This change moves optimized callbacks from each .o file to compiler-rt. Instead of using code generation it uses direct assembly implementation. Please note that the 'or' version is not implemented and it will produce unresolved external if somehow 'or' version is requested.
