[Lldb-commits] [PATCH] D67869: [ABISysV] Fix regression for Simulator and MacABI

The ABISysV ABI was refactored in r364216 to support the Windows ABI for x86_64. In particular it changed `ABISysV_x86_64::CreateInstance` to switch on the OS type. This breaks debugging MacABI apps as well as apps in the simulator. This adds back the necessary cases.

We have a test internally that exercises this code path but some MacABI parts are still missing upstream.
