gimple-fold: Recompute ADDR_EXPR flags after folding a TMR [PR98268]
The gimple verifier picked up that an ADDR_EXPR of a MEM_REF was not
marked TREE_CONSTANT even though the address was in fact invariant.
This came from folding a &TARGET_MEM_REF with constant operands to
a &MEM_REF; &TARGET_MEM_REF is never treated as TREE_CONSTANT
but &MEM_REF can be.

* gimple-fold.c (maybe_canonicalize_mem_ref_addr): Call
recompute_tree_invariant_for_addr_expr after successfully
folding a TARGET_MEM_REF that occurs inside an ADDR_EXPR.
