Filipe Cabecinhas 465a5041e9 [NFC] Remove some dead code:
DbgInfoIntrinsic::StripCast() is dead since r79977
The only function that creates Comdat objects seems to be in Module, and always creates them using the default constructor.

David Majnemer dad0a645a7 IR: Add COMDATs to the IR
This new IR facility allows us to represent the object-file semantic of
a COMDAT group.

COMDATs allow us to tie together sections and make the inclusion of one
dependent on another. This is required to implement features like MS
ABI VFTables and optimizing away certain kinds of initialization in C++.

This functionality is only representable in COFF and ELF, Mach-O has no
similar mechanism.
