Subject: [PATCH 1/2] [lldb] Treat user aliases the same as built-ins when tab
completing
Previously we would check all built-ins first for suggestions,
then check built-ins and aliases. This meant that if you had
an alias brkpt -> breakpoint, "br" would complete to "breakpoint".
Instead of giving you the choice of "brkpt" or "breakpoint".
