libstdc++: Rearrange tests for <bitset>

In C++03 std::bitset was in the Container clause, but since C++11 it has
been in the Utilties clause. This moves the tests to the 20_util
directory, where most people probably expect to find them.

Also create 'access', 'observers', and 'io' subdirectories and group
some tests under there, rather than having one directory per function
name, and only a single test in that directory.
