[DebugInfo] Fix debug info round tripping of types inside functions

Browse Source 
Types with @_originallyDefinedIn cannot be round tripped,

Types declared inside functions have their mangling affected by the
function signature. If the generic signature mentions an
@_originallyDefinedIn type, the type inside the function cannot be round
tripped either.

This commit disables round tripping for this scenario.
