Attach attribute "trap-func-name" to call sites of llvm.trap and llvm.debugtrap. This is needed to use clang's command line option "-ftrap-function" for LTO and enable changing the trap function name on a per-call-site basis. rdar://problem/21225723 Differential Revision: http://reviews.llvm.org/D10831 llvm-svn: 241306
