    RISC-V/testsuite: Fix ILP32 RVV failures from missing <gnu/stubs-ilp32d.h>
    
    In non-multilib installations system headers may not be available for
    compilation options using a non-default model, causing build errors such
    as:
    
    In file included from .../include/features.h:527,
                     from .../include/assert.h:35,
                     from .../gcc/testsuite/gcc.target/riscv/rvv/autovec/vmv-imm-template.h:2,
                     from .../gcc/testsuite/gcc.target/riscv/rvv/autovec/vmv-imm-fixed-rv32.c:4:
    .../include/gnu/stubs.h:11:11: fatal error: gnu/stubs-ilp32d.h: No such file or directory
    
    Therefore we have to be very cautious when trying to use a non-default
    model in the testsuite, preferably avoiding to rely on headers that have
    not been supplied by GCC itself, or otherwise verifying in a preparatory
    step whether the given model is buildable in a given test environment.
    
    In this case however we can easily avoid the issue, because <assert.h>
    facilities are not used at all by "vmv-imm-template.h", which includes
    the header.  Remove the inclusion then, turning these issues:
