* tree-ssa-operands.c (get_expr_operands): Cleanup handing of
MEM_REF and INDIRECT_MEM_REF.
* tree-def.c (IDX_EXPR): Fix typos.
(BIT_FIELD_EXPR): Likewise.
* gimple-low.c (lm_get_inner_reference): Handle large bit-field
references with unaligned accesses.
* tree-ssa-pre.c (phi_translate_1): Add support for IDX_EXPR,
MEM_REF and INDIRECT_MEM_REF.
(valid_in_sets): Likewise.
(create_expression_by_pieces): Likewise.
(can_value_number_operation): Likewise. Exclude invariant
POINTER_PLUS_EXPRs.
(can_PRE_operation): Likewise.
(create_value_expr_from): Add support for IDX_EXPR.
(poolify_tree): Add support for INDIRECT_MEM_REF.
(insert_fake_stores): Likewise.
(gate_pre): Enable.
* tree-ssa-loop-im.c (stmt_cost): Give IDX_EXPR the same cost
as MULT_EXPR.
* tree-ssa-sccvn.c (copy_reference_ops_from_ref): Handle
invariant addresses with POINTER_PLUS_EXPR.
(visit_unary_op): Merge with visit_binary_op as visit_nary_op.
(simplify_binary_expression): Rewrite to handle all nary
expressions.
(try_to_simplify): Adjust accordingly. Add more tcc_expression
trees as supported.
