[PATCH, committed] Fix DOM bootstrap failure

- Subject: [PATCH, committed] Fix DOM bootstrap failure
The recent DOM patch for boolean types passed element->rhs as an
argument to a function after the structure had been freed. Oops. This
caused a bootstrap failure on AIX.
Committed as obvious.

* tree-ssa-dom.c (lookup_avail_expr): Do not pass member in freed
structure as argument.
