discriminators: Fix assigning discriminators on edge [PR113546]
The problem here is there was a compare debug since the discriminators
would still take into account debug statements. For the edge we would look
at the first statement after the labels and that might have been a debug
statement.
So we need to skip over debug statements otherwise we could get different
discriminators # with and without -g.
Bootstrapped and tested on x86_64-linux-gnu with no regressions.
