This is a fairly mechanical change, it just moves each algorithm into its own header. This is intended to be a NFC. This commit re-applies 7ed7d4ccb899, which was reverted in 692d7166f771 because the Modules build got broken. The modules build has now been fixed, so we're re-committing this. Differential Revision: https://reviews.llvm.org/D103583 Attribution note ---------------- I'm only committing this. This commit is a mix of D103583, D103330 and D104171 authored by: Co-authored-by: Christopher Di Bella <cjdb@google.com> Co-authored-by: zoecarver <z.zoelec2@gmail.com>
