* c-common.c (c_address_looks_like_offsetof): New.
* c-common.h (c_address_looks_like_offsetof): Declare.
* c-typeck.c (build_unary_op) <ADDR_EXPR>: Use it. Don't lower
address references not destined for offsetof.
(c_expand_return): Only look inside ARRAY_REF and COMPONENT_REF
when looking for returning address of local variable.
* expr.c (expand_expr_1): Don't dereference size
of unbounded arrays.
* gimplify.c (gimplify_addr_expr): Only fold
address of variable size array elements.
* tree-simple.c (is_gimple_min_invariant): Also check
is_gimple_variable before disallowing offset address for type.
* tree-ssa-ccp.c (maybe_fold_offset_to_aggregate_ref): New.
(maybe_fold_offset_to_component_ref): Use it.
(maybe_fold_stmt_indirect, maybe_fold_stmt_plus): Likewise.
(maybe_fold_offset_to_array_ref): Likewise.
Don't fail for division remainder non-zero.
* varasm.c (initializer_constant_valid_p) <ADDR_EXPR>: Use
handled_component_p and look inside references.
<MINUS_EXPR>: Always look past widening casts.
