[Bug tree-optimization/23086] New: gcc.dg/tree-ssa/20030807-7.c should be fixed properly

["dnovillo at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The hack in may_alias_p we used to have was papering over the real problem and
causing problems (PR 22591).

The real fix is to notice in the aliaser that a default definition for a
PARM_DECL cannot possibly point to a local variable.

Test XFAIL'd for now.  Fix scheduled for 4.2.
