Their motivation is somewhat arbitrary, but generally, clang-cl supports a variety of extensions, some inherited from GCC, in all modes. Part of the point of switching compilers from MSVC to clang is to get access to those extensions.

I might be mistaken here  but couldn't this be done by introducing an option and tying it to setting the AssemblerDialect field in the target's respective `MCAsmInfo` instance and then querying that? Wouldn't this remove the dependency on setting the dialect on the parser. Module level assembly are only going to be treated as GNU statements (from Uli's comment above), and if its just the case of using a different variant (within the gnu dialect), then this can be set in the respective (Target)MCAsmInfo instances appropriately?
