<pre>Running `opt -O1` on call-guard.ll produces different output with/without debug
info present. To reproduce the issue, do:
# Baseline
$ $OPT -O1 test/Transforms/InstCombine/call-guard.ll -S -o -
# With debug info
$ $OPT -O1 test/Transforms/InstCombine/call-guard.ll -o - -debugify-each
-debugify-quiet | $OPT -strip -S
Comparing: -O1 test/Transforms/InstCombine/call-guard.ll
Baseline: /var/folders/j8/t4w0bp8j6x1g6fpghkcb4sjm0000gp/T/tmp.RGoONn6d
With DI : /var/folders/j8/t4w0bp8j6x1g6fpghkcb4sjm0000gp/T/tmp.9KJlc8DB
