Assembler output when using -Z asm-comments emits long sequences of empty lines (hundreds to thousands)

[sivadeilra]

Run rustc -Z asm-comments --emit asm ..., and look at the generated assembly code. It will often have very long sequences of empty lines, or lots of blocks like this:

    #NO_APP
    #APP

    #NO_APP
    #APP

    #NO_APP
    #APP

    #NO_APP
    #APP

    #NO_APP
    #APP

    #NO_APP
    #APP

    #NO_APP
    #APP

It would be best to collapse all contiguous blank lines into a single blank line, and to drop back-to-back #NO_APP / #APP markers.

I can not reproduce this issue. Emitted asm looks fine to me...

I can't reproduce this either with a recent nightly, rustc 1.9.0-nightly (924da29 2016-04-10).
Probably should be closed, unless there is a source code example that demonstrates the issue.
