Support enabling tsan and ubsan from Xcode UI

Xcode won't let you enable ubsan from the UI as it requires a
'Compile Sources' phase with (Objective-)C(++) sources, but if you
manually edit the scheme and enable it or equivalently add the phase
with a dummy file, enable it from the UI, and then remove the phase,
ubsan will work.
