[ABISysV] Fix regression for Simulator and MacABI

Authored by JDevlieghere on Sep 20 2019, 4:37 PM.



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 on Github that exercises this code path and which I'd like to upstream once the remaining MacABI parts become available in clang.

Can you add a comment here that this is to support older compilers that don't support the -simulator environment yet?

What does x86_64-apple-darwin canonicalize to? Do we need an extra case for that?
