    d: Fix error: aggregate value used where floating point was expected

    Casting from vector to static array is permitted, and the frontend
    generates a reinterpret cast, but casting back the other way resulted in
    an error.  This has been fixed to be properly handled in the code
    generation pass of VectorExp, and the conversion for lvalue and rvalue
    handling done in convert_expr and convert_for_rvalue respectively.

            PR d/106139

    gcc/d/ChangeLog:

            * d-convert.cc (convert_expr): Handle casting from array to vec=
tor.
            (convert_for_rvalue): Rewrite vector to array casts of the same
            element type into a constructor.
            (convert_for_assignment): Return calling convert_for_rvalue.
            * dmd/expressionsem.c (ExpressionSemanticVisitor::visit): Run
semantic
            on vector expression after lowering.
            * expr.cc (ExprVisitor::visit (VectorExp *)): Handle generating=
 a
            vector expression from a static array.

    gcc/testsuite/ChangeLog:

            * gdc.dg/pr106139a.d: New test.
            * gdc.dg/pr106139b.d: New test.
            * gdc.dg/pr106139c.d: New test.
            * gdc.dg/pr106139d.d: New test.
