<pre>Running `opt -O1` on this file produces different output with/without debug
info present. To reproduce the issue, do:
# Baseline
$ $OPT -O1 $FILE -S -o -
# With debug info
$ $OPT -O1 $FILE -o - -debugify-each -debugify-quiet | $OPT -strip -S
Comparing: -O1 test/Transforms/GuardWidening/range-check-merging.ll
Baseline: /var/folders/j8/t4w0bp8j6x1g6fpghkcb4sjm0000gp/T/tmp.C74Q3eA7
With DI : /var/folders/j8/t4w0bp8j6x1g6fpghkcb4sjm0000gp/T/tmp.7O0SBoIr
