* fold-const.c (operand_equal_p): Compare INTEGER_CST array
indices by value.
* gimplify.c (canonicalize_addr_expr): To be consistent with
gimplify_compound_lval only set operands two and three of
ARRAY_REFs if they are not gimple_min_invariant. This makes
it never at this place.
* tree-ssa-ccp.c (maybe_fold_offset_to_array_ref): Likewise.
* g++.dg/tree-ssa/pr31307.C: New testcase.
* gcc.dg/tree-ssa/pr24689.c: Likewise.
