    [aarch64] [testsuite] disable PIE for nonlocal_goto sme tests
    
    When an aarch64 toolchain is configured with --enable-default-pie,
    gcc.target/aarch64/sme/nonlocal_goto_[123].c fail because ira.cc's
    setup_reg_equiv resets function_invariant_p(x) equivalences when
    e.g. flag_pic and !CONSTANT_P (x), and then lra ends up unable to
    rematerialize stack addresses that would otherwise be rematerialized
    as small constants added to sp, and instead the addresses end up in
    pseudos assigned to stack slots.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.target/aarch64/sme/nonlocal_goto_1.c: Force PIE off.
            * gcc.target/aarch64/sme/nonlocal_goto_2.c: Likewise.
            * gcc.target/aarch64/sme/nonlocal_goto_3.c: Likewise.
