scoped tables: insert before further lookups

Avoid hash table lookups between requesting an insert and storing the
inserted value in avail_exprs_stack.  Lookups before the insert is
completed could fail to find double-hashed elements.

for  gcc/ChangeLog

* tree-ssa-scopedtables.cc
(avail_exprs_stack::lookup_avail_expr): Finish hash table
insertion before further lookups.
