B2recomp: static recompilation of Bayonetta 2

B2recomp is an unofficial static recompilation of the Nintendo Switch version of Bayonetta 2 for Windows. The README says it translates that version's AArch64 program code to C on the user's PC from the user's dumped copy, then runs it with a reimplemented system layer and maps the NVN graphics API to Vulkan.
