I'm trying to find if D has any built in special integer 
operations like bit reverse, population count, count leading 
zeroes, count trailing zeroes. Many ISAs have dedicated 
instructions for these kinds of operations. I haven't found any 
of these in the documentation, either implemented as fallback D 
code or working directly on the ISA instructions.

Do these exist or do you have to create these yourselves or 
resort to compiler intrinsics?
