  Log Message:
  -----------
  [llvm-profgen] Preserve zero-valued first PT_LOAD address (#212258)

FirstLoadableAddress was initialized with if (!FirstLoadableAddress), so
a valid first PT_LOAD at vaddr 0 was treated as unset and overwritten by
a later segment. Track whether the first loadable segment has been seen
instead.
