Improve FastUniformBits performance for std::minstd_rand.
The rejection algorithm was too pessimistic before, and not in line with the [rand.adapt.ibits]. Specifically, when sampling from an URBG with a non power of 2 range, FastUniformBits constructed a rejection threshold with a power-of-2 range that was too restrictive.
For example, minstd_rand has a range of
[1, 2147483646], which has a range of 2145386495, or about 30.999 bits.
Before FastUniformBits rejected values between 1<<30 and 2145386495, which includes approximately 50% of the generated values. However, since a minimum of 3 calls are required to generate a full 64-bit value from an entropy pool of 30.9 bits, the correct value for rejection sampling is the range value which masks 21 (0x7fe00000) or 22 bits and rejects values greater than that. This reduces the probability of rejecting a sample to about 0.1%
NOTE: Abseil random does not guarantee sequence stability over time, and this is expected to change sequences in some cases.
