Add a -disable-cfi option to llvm-mc. This is useful for debugging as
it will expand any .cfi_* directives in the input assembly. Unfortunately this cannot replace elf-dump in tests as the asm streamer cannot relax the line advance opcodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168522 91177308-0d34-0410-b5e6-96231b3b80d8
