Handle gnu pubtypes sections:
a) Make sure we are emitting the correct section in our section labels when we begin the module. b) Make sure we are emitting the correct pubtypes section in the presence of gnu pubtypes. c) For C++ struct, union, class, and enumeration types are default external. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191225 91177308-0d34-0410-b5e6-96231b3b80d8
