<pre>I rebuilt/installed mesa earlier this evening and not long after, my system
hung.
Upon reboot, the GDM login screen was corrupted and attempts to login caused
gnome-shell to crash almost immediately after.
Hardware: AMD Ryzen R7 1700, Radeon HD 7850 1GB
Software: Ubuntu 17.04 64-bit with LLVM/Mesa from trunk/git.
A bisect run shows this as the culprit:
8ec4975cd83365c791a1852a6515ed5d4ade2daf is the first bad commit
commit 8ec4975cd83365c791a1852a6515ed5d4ade2daf

st_glsl_to_tgsi: don't try and pass 32-bit values to get_deref_offsets
Just use a temporary 16-bit index.
This fixes coverity issue, pointed to me by Ilia.
