tree-ssa-dom.c (avail_exprs_stack): New global varray.
* tree-ssa-dom.c (avail_exprs_stack): New global varray.
(struct dom_walk_block_data): Remove avail_exprs member.
(tree_ssa_dominator_optimize): Initialize avail_exprs_stack.
(lookup_avail_expr): No longer need to pass in address of
the block local available exprs stack. All callers changed.

(simplify_switch_and_lookup_avail_expr): Similarly.
(get_eq_expr_value, record_cond): Likewise.
(record_dominating_conditions): Likewise.
(update_rhs_and_lookup_avail_expr): Likewise.
(record_equivalences_from_stmt): Likewise.
(dom_opt_initialize_block_local_data): No longer test state of
block local avail_exprs.
(dom_opt_initialize_block): Mark unwind point in the global
avail_expr stack.
(remove_expressions_from_table): Update to unwind to the
most recent unwind marker in the global avail_expr stack.
All callers changed.

avail_expr stack as needed.
(record_cond): Push elements into the global avail_exprs stack.
