While revisiting VIS, *please* consider fixing a big usability
problem: the pack and aligndata builtins don't take GSR in
account; it has unknown state and might be changed as a
side-effect of a previous VIS insn (well, alignaddr). The
affected builtins don't have dependencies to GSR or a means to
set it besides in an asm; hardly usable at all. See PR48974.
