* tree-ssa-math-opts.c (struct symbolic_number): Store type of
expression instead of its size.
(do_shift_rotate): Adapt to change in struct symbolic_number. Return
false to prevent optimization when the result is unpredictable due to
arithmetic right shift of signed type with highest byte is set.
(verify_symbolic_number_p): Adapt to change in struct symbolic_number.
(find_bswap_1): Likewise. Return NULL to prevent optimization when the
result is unpredictable due to sign extension.
(find_bswap): Adapt to change in struct symbolic_number.

* gcc.c-torture/execute/pr61306-1.c: New test.
* gcc.c-torture/execute/pr61306-2.c: Likewise.
* gcc.c-torture/execute/pr61306-3.c: Likewise.
