* tree-ssa-ccp.c (fold_stmt_r): DATA argument is now a pointer
to a structure containing state rather than a pointer to bool.
(case ARRAY_REF): New code to handle folding some array references.
(case ADDR_EXPR): Note when we are processing expressions found
within an ADDRE_EXPR.
(fold_stmt, fold_stmt_inplace): Pass in a structure to fold_stmt_r
for state variables rather than just a pointer to a boolean.
* tree-ssa-dom.c (simplify_rhs_and_lookup_avail_expr): Remove
handling of constant string references.
* gcc.dg/tree-ssa/foldstring-1.c: New test.
