Log:
    PR tree-optimization/60823
    * omp-low.c (ipa_simd_modify_function_body): Go through
    all SSA_NAMEs and for those refering to vector arguments
    which are going to be replaced adjust SSA_NAME_VAR and,
    if it is a default definition, change it into a non-default
    definition assigned at the beginning of function from new_decl.
    (ipa_simd_modify_stmt_ops): Rewritten.
    * tree-dfa.c (set_ssa_default_def): When removing default def,
    check for NULL loc instead of NULL *loc.

    * c-c++-common/gomp/pr60823-1.c: New test.
    * c-c++-common/gomp/pr60823-2.c: New test.
    * c-c++-common/gomp/pr60823-3.c: New test.
