    d: Fix no NRVO when returning an array of a non-POD struct

    TREE_ADDRESSABLE was not propagated from the RECORD_TYPE to the ARRAY_T=
YPE,
so
    NRVO code generation was not being triggered.

    gcc/d/ChangeLog:

            PR d/96157
            * d-codegen.cc (d_build_call): Handle TREE_ADDRESSABLE static
arrays.
            * types.cc (make_array_type): Propagate TREE_ADDRESSABLE from b=
ase
            type to static array.

    gcc/testsuite/ChangeLog:

            PR d/96157
            * gdc.dg/pr96157a.d: New test.
            * gdc.dg/pr96157b.d: New test.
