    PR libstdc++/52699
    * include/bits/random.tcc (independent_bits_engine<>::operator()())
    Avoid various overflows; use common_type on result_type and
    _RandomNumberEngine::result_type; avoid floating point computations;
    other smaller tweaks.

    * include/bits/random.tcc (uniform_int_distribution<>::operator())
    Use common_type; assume _UniformRandomNumberGenerator::result_type
    unsigned; tidy.

    * include/bits/stl_algobase.h (__lg(unsigned), __lg(unsigned long),
    __lg(unsigned long long)): Add.
