This typedef doesn't match the signature below, specifically the signature
takes a `lldb:SBDebugger` vs this was defined as `lldb:SBDebugger&`.
```
lldb/source/API/SBDebugger.cpp:199:13: runtime error: call to function
lldb::PluginInitialize(lldb::SBDebugger) through pointer to incorrect function
type 'bool (*)(lldb::SBDebugger &)'
.../CustomPlugin.cpp:134: note: lldb::PluginInitialize(lldb::SBDebugger)
defined here
```
