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.

Ah good point, these functions are polluting the output indeed. Thanks for the pointers 👍
