[Bug 78468] Compiling of shader gets stuck in infinite loop

--- Comment #11 from Iago Toral <itoral at igalia.com> ---
The bad commit mentioned above seems to avoid making temporary variables for
rvalues in certain scenarios where, in theory, we do not need them. After that
commit, do_assignment() in ast_to_hir.cpp takes a needs_rvalue parameter to
decide if we need to compute the rvalue or not. In that same commit, this
parameter is set to false in a number of situations.

I did a quick test switching this parameter to true in all the cases and that
seems to fix the problem for me, so I guess there is one case where we are
wrongly passing false and for some reason that produces this recurrent
behavior, I suppose because it really needs to compute an rvalue that never
gets computed. I'll see if I can find more.
