* tree.h (tree_expr_nonzero_p): Export.
* fold-const.c (tree_expr_nonzero_p): Likewise.
Return true for CALL_EXPRs that are alloca calls.
(fold_binary): Use omit_one_operand when checking EQ_EXPRs or NE_EXPRs
against zero.
* tree-flow.h (expr_computes_nonzero): Remove.
* tree-vrp.c (expr_computes_nonzero): Remove.
(vrp_expr_computes_nonzero): Use tree_expr_nonzero_p.
(extract_range_from_unary_expr): Likewise.
* tree-ssa-dom.c (record_equivalences_from_stmt): Use
tree_expr_nonzero_p.
