tree-optimization/94266 - fix object type extraction heuristics
This fixes the heuristic deriving an actual object type from a
MEM_REFs pointer operand to use the more sensible type of an
actual object instead of the pointed to type.

* gimple-ssa-sprintf.c (get_origin_and_offset): Use the
type of the underlying object to adjust for the containing
field if available.
