tree-optimization/104511 - avoid FP to DFP conversion for VEC_PACK_TRUNC
This avoids forwprop from matching DFP <-> FP vector conversions
using VEC_[UN]PACK{_TRUNC,_LO,_HI}. Maybe DFP vectors shouldn't be
a thing, but they appearantly are. Re-using CONVERT/NOP_EXPR for
DFP <-> FP conversions was probably a mistake.

touching DFP <-> FP conversions.
