* tree-vectorizer.c (supportable_widening_operation): Determine
signedness of FIX_TRUNC_EXPR from output operand.
(supportable_narrowing_operation): Ditto.
* tree-vect-generic.c (expand_vector_operations_1): Determine
signedness of VEC_UNPACK_FLOAT_HI_EXPR and VEC_UNPACK_FLOAT_LO_EXPR
from input operand.
