"Hello, world" -- although any program should trigger the same bug

Something seems to be screwed up with the way the x86_64 code generator is
mapping metadata to assembly directives.  The following works fine:

  $ clang -emit-llvm -S -o hello.ll hello.c
  $ llvm-as hello.ll
  $ llvm-ld -native -o hello hello.bc

However, when I compile with -g, badness happens:

  $ clang -g -emit-llvm -S -o hello.ll hello.c
  $ llvm-as hello.ll
  $ llvm-ld -native -o hello hello.bc
  hello.s: Assembler messages:
  hello.s:2: Error: junk at end of line, first unrecognized character is `"'
  llvm-ld:
  $ head hello.s
      .file   "hello.bc"
      .file   1 "/tmp" "hello.c"
