glsl/ast: Generate a more compact expression to disable execution of default case
Instead of generating a sequence like:
run_default = true;
if (i == 3) // some label that appears after default
run_default = false;
if (i == 4) // some label that appears after default
run_default = false;
...
if (run_default) {
...
}
generate something like:
run_default = !((i == 3) || (i == 4) || ...);
if (run_default) {
...
}
This eliminates one use of conditional assignment, and it enables the
elimination of another.
