  Log Message:
  -----------
  In dynamic instrumentation, springboards are installed immediately after
users insert a snippet. The user can continue to insert more snippets to
the same function, which will trigger Dyninst to perform the additional
relocation. So, we need to overwrite existing springboard for newly added
instrumentations.

In other words, we need to overwrite existing springboards if the existing
ones were installed in previous relocations.
