[committed] libstdc++: Rename _UniformRandomNumberGenerator parameters

[Jonathan Wakely via Gcc-patches]

The paper P0346R1 renamed uniform random number generators to
uniform random bit generators, to describe their purpose more
accurately. This makes that same change in one of the relevant
files (but not the others).

libstdc++-v3/ChangeLog:

        * include/bits/uniform_int_dist.h (uniform_int_distribution):
        Rename _UniformRandomNumberGenerator template parameters to
        _UniformRandomBitGenerator, as per P0346R1.

Tested x86_64-linux. Committed to trunk.
