    d: Fix small struct literals that have non-deterministic hash values

    Same issue as the initial commit that addressed PR96153, only this time to
fix
    it also for structs that are not returned in memory.  Tests have been added
    that triggered an assertion on x86_64, however the original test was
failing
    on SPARC 64-bit targets.

    gcc/d/ChangeLog:

            PR d/96153
            * d-codegen.cc (build_address): Create a temporary for CALL_EXPRs
            returning trivial aggregates, pre-filling it with zeroes.
            (build_memset_call): Use build_zero_cst if setting the entire
object.

    gcc/testsuite/ChangeLog:

            PR d/96153
            * gdc.dg/pr96153.d: Add new tests.
