This was sometimes causing clang or llvm-mc to crash, and in other cases could emit a bogus DWARF line-table header. I did an interim patch in r352541; this patch should be a cleaner and more complete fix, and retains the test. Addresses PR40538. Differential Revision: https://reviews.llvm.org/D58750 llvm-svn: 355226
