Summary: DWARF 5 proposes a reinvented .debug_macro section. This change follows that spec. Currently, only GCC produces the .debug_macro section and hence the added test is annottated with expectedFailureClang. Reviewers: spyffe, clayborg, tberghammer Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D15437 llvm-svn: 255729
