Zachary Turner a7b041748d [CodeView] Don't output S_UDT symbols for forward decls. ... S_UDT symbols are the debugger's "index" for all the structs, typedefs, classes, and enums in a program. If any of those structs/classes don't have a complete declaration, or if there is a typedef to something that doesn't have a complete definition, then emitting the S_UDT is unhelpful because it doesn't give the debugger enough information to do anything useful. On the other hand, it results in a huge size blow-up in the resulting PDB, which is exacerbated by an order of magnitude when linking with /DEBUG:FASTLINK. With this patch, we drop S_UDT records for types that refer either directly or indirectly (e.g. through a typedef, pointer, etc) to a class/struct/union/enum without a complete definition. This brings us about 50% of the way towards parity with /DEBUG:FASTLINK PDBs generated from cl-compiled object files.
