If I'm reading things right, pass_update_address_taken is never actually
used.
Deleting it, I was able to still successfully bootstrap on
x86_64-unknown-linux-gnu (using gcc-4.7.2-2.fc17.x86_64).
The use of the pass appears to have been removed in:
http://gcc.gnu.org/r164525
Should I remove it from trunk?
