This patch actually a small corrections of my patch for PR37514. It should behave the same way as the previous patch in all situations when gcc with the previous patch is not aborting on gcc_assert. So I believe the patch is safe.

Successfully bootstrapped and tested on x86_64 and ia64 (a target with heavy usages of INC/DEC addressing).

Ok to commit?
