If I have an RTL dump and I want to understand how an insn was changed
from one pass to another, I can look at the INSN_UID in the dump and
set conditional breakpoints for that insn.
If I see a statement change between two *.txx dumps, what is the
analogous mechanism for making a conditional breakpoint to look at
that statement?
