zoecarver 7ed7d4ccb8 [libcxx][gardening] Move all algorithms into their own headers.
This is a fairly mechanical change, it just moves each algorithm into its own header. This is a NFC.

Note: during this change, I burned down all the includes, so this follows "include only and exactly what you use."
