Problem with optimization passes management

[Wolfgang Gellerich]

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.

Regards, Wolfgang
