  Log Message:
  -----------
  Propagate lifetimebound from formal parameters to those in the canonical declaration and use that for analysis (#107627)

This partially fixes #62072 by making sure that re-declarations of a
function do not have the effect of removing lifetimebound from the
canonical declaration.

It doesn't handle the implicit 'this' parameter, but that can be
addressed in a separate fix.
