eliminate EOL, adding all comments with the OutStreamer.AddComment
method. With this, comments should end up on the same lines as the .byte directives (for example) and we now get no output with: $ llc CodeGen/X86/2009-02-12-DebugInfoVLA.ll -o - -filetype=null -asm-verbose woot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98105 91177308-0d34-0410-b5e6-96231b3b80d8
