* fold-const.c (try_move_mult_to_index): Handle INTEGER_CST
and generic summands for char* as s * delta, too, folding &a[i]
CODE x to &a[i CODE x/s]. Use tree_int_cst_equal
for comparison of steps. Convert types for index addition.
(fold_binary): Adjust the callers to always dispatch to
try_move_mult_to_index.
* tree-ssa-propagate.c (set_rhs): Avoid setting rhs to
expr with non-gimple ARRAY_REF offset.
* g++.dg/tree-ssa/pr19807.C: New testcase.
