Problem with optimization passes management

- Subject: Problem with optimization passes management
There is a conflict between the command line switches that turn off individual
optimization steps and their preconditions. Compiling a "hello world" with the
following options:
-O1 -fno-tree-salias
causes gcc to fail with an internal consistency check. Pass return_slot has
PROP_alias in its preconditions but alias information is not generated due to
the second option.
