Summary:
This fixes symbolization in Standalone UBSan mode for the Darwin simulators.
861b69f (rdar://problem/58789439) tried to fix
symbolization for all sanitizers on Darwin simulators but unfortunately it only
fixed the problem for TSan.
For UBSan in standalone mode the fix wasn't sufficient because UBSan's
standalone init doesn't call
Symbolizer::LateInitialize()
like ASanand TSan do. This meant that
AtosSymbolizerProcess::LateInitialize()
was never being called before
AtosSymbolizerProcess::StartSymbolizerSubprocess()
which breaks aninvariant we expect to hold.
The missing call to
Symbolizer::LateInitialize()
during UBSan'sstandalone init seems like an accidently omission so this patch simply
adds it.
