This is dead code since PIC16 was removed in 2010. The result was an odd mix, where some parts would carefully pass it along and others would assert it was zero (most of the object streamer for example). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185436 91177308-0d34-0410-b5e6-96231b3b80d8
