  Log Message:
  -----------
  Teach LLDB's pretty-printer about libc++'s various `std::vector` layouts (#202438)

PR #155330 changes `std::vector` from unconditionally using three
pointers to represent its layout to potentially using three pointers or
a begin pointer and two integers. This commit changes LLDB so that it
can robustly work with the legacy vector layout, the new pointer layout,
and the new size-based layout.
