Currently in some cases lldb reports stop reason as "step out" or "step over" (from thread plan completion) instead of "breakpoint", if the user breakpoint happens to be set on the same address.
The part of f08f5c9926 seems to overwrite internal breakpoint detection logic, so that only the last breakpoint for the current stop address is considered.
Together with step-out plans not clearing its breakpoint until they are destrouyed, this creates a situation when there is a user breakpoint set for address, but internal breakpoint makes lldb report a plan completion stop reason instead of breakpoint.
This patch reverts that internal breakpoint detection logic to consider all breakpoints
