  [lld][BP] Print total size of startup symbols (#145106)

A good proxy to estimate the number of page faults during startup is the
total size of startup functions. Assuming profiles are up-to-date, we
can measure this total size pretty easily. Note that if profile data is
old, this number could be wrong.
