[LTO][Legacy] Add new API to query Mach-O CPU (sub)type

Authored by thegameg on Feb 24 2020, 10:57 AM.



Tools working with object files on Darwin (e.g. lipo) may need to know properties like the CPU type and subtype of a bitcode file. The logic of converting a triple to a Mach-O CPU_(SUB_)TYPE should be provided by LLVM instead of relying on tools to re-implement it.
