As in title, 
https://github.com/llvm/llvm-project/commit/a8f43974260ec244d78336d2530f8fc097753580
 broke CI due to the calling convention not available on certain targets. This 
patch uses a simpler calling convention and enables the test only when the 
attribute exists. It's verified that this test crashes the compiler before 
a8f43974260ec244d78336d2530f8fc097753580 so it's the same effect as the 
previous test. Disabling the test on platforms that don't have the calling 
convention is fine because it's guarding against a frontend bug.
