[PATCH] D125970: [amdgpu] Add amdgpu_kernel calling conv attribute to clang

[Aaron Ballman via Phabricator via cfe-commits]

> The primary application is for more rapid debugging of the amdgpu backend by permuting a C or C++ test file instead of manually updating an IR file.

Given that this is adding a calling convention, which has significant impacts on our type system: is this use case important enough to steal a bit for this CC? This sounds *super* special case to me, but maybe it's a common need?
