Hello!
We should not update ticks of instructions, dependent on debug
instruction. Without the patch, the scheduling order depends on the
presence of debug instructions and leads to -fcompare-debug failures.

* gcc.dg/pr56023.c: New test.
Tested on 4.6 branch on alpha-linux-gnu, where it fixes the bootstrap
failure and x86_64-pc-linux-gnu {,-m32}.
The patch should be applied to 4.7 and 4.8 branches as well. Patch was
also tested on mainline x86_64-pc-linux-gnu {,-m32}.
OK for 4.6, 4.7 and mainline?
Ok. Thanks for working on this, Uros.
