Switch more of Sema::CheckInitializerTypes over to
InitializationSequence. Specially, switch initialization of a C++
class type (either copy- or direct-initialization). 

Also, make sure that we create an elidable copy-construction when
performing copy initialization of a C++ class variable. Fixes PR5826.
