re PR middle-end/21897 (Segementation fault in fold_ternary)

* fold-const.c (operand_equal_p): Don't return 1, if element
chains for 2 VECTOR_CSTs are not the same length.

PR regression/21897
* fold-const.c (fold_ternary) <case BIT_FIELD_REF>: Don't crash if
not all VECTOR_CST elements are given.
