glsl_to_tgsi: fix a bug in eliminate_dead_code_advanced()

The bug, reported to me by Vadim Girlin on IRC, was causing overzealous
elimination of code in parallel if statements such as the following:

if (x) {
r = false;
}
if (y) {
r = true;
}

Before this commit, the assignment inside the first if block would be
misdetected as dead code and removed.
