Soften BitSet class comment. 

std::bitset<> doesn't have exact replacements for all of the
functionality of BitSet32/64, so there are still places we want to use
these classes.

Bug: 160010896
Test: test BitSet_test.cpp

/*

/*

 * Contains some bit manipulation helpers.

 * A class to provide efficient manipulation of bitsets.

 *

 *

 * DO NOT USE: std::bitset<32> or std::bitset<64> preferred

 * Consider using std::bitset<32> or std::bitset<64> if all you want is a class to do basic bit

 * manipulation (i.e. AND / OR / XOR / flip / etc). These classes are only needed if you want to

 * efficiently perform operations like finding the first set bit in a bitset and you want to

 * avoid using the built-in functions (e.g. __builtin_clz) on std::bitset::to_ulong.
