Ulrich Weigand f43b510015 [SystemZ] Make better use of VLDEB ...

We already have special code (DAG combine support for FP_ROUND)
to recognize cases where we an use a vector version of VLEDB to
perform two floating-point truncates in parallel, but equivalent
support for VLEDB (vector floating-point extends) has been
missing so far.  This patch adds corresponding DAG combine
support for FP_EXTEND.
