First, allow the case for negative powers of two. Then ensure that we
use the absolute value of the non-constant value to calculate the
quotient -- this was hinted in the code by the name 'uq'.
This fixes an issue when 'd' is positive and 'n' is negative. The
ishr will propagate the negative sign and we'll use nir_ineg() again,
incorrectly.
v2: First version used only ishr, but that isn't sufficient, since it
never can produce a zero as a result. (Jason)
Allow negative powers of two. (Caio)

Support
-------
Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.
The next best option is to ask your question in an email to the
mailing lists: `mesa-dev\@lists.freedesktop.org
