    rs6000: MMA builtin usage ICEs when used in a #pragma omp parallel and
using -fopenmp [PR100777]

    Using an MMA builtin within an openmp parallel code block, leads to an SSA
    verification ICE on the temporaries we create while expanding the MMA
builtins
    at gimple time.  The solution is to use create_tmp_reg_or_ssa_name(), which
    knows when to create either an SSA or register temporary.
