Comment out or flag compiler generated functions

[tomsons26]

The PDB format uses pseudo and compgenx flags to specify these functions
https://github.com/microsoft/microsoft-pdb/blob/master/include/cvinfo.h#L1145
for example public: void __dflt_ctor_closure(); is one such function but there are less obvious ones like copy ctors, copy operators and other things that are not clear if they were actually implemented.
