2; Make sure FastISel report a warming when we asked it to do so.
3; Note: This test needs to use whatever is not supported by FastISel.
4;       Thus, this test may fail because inline asm gets supported in FastISel.
5;       To fix this, use something else that's not supported (e.g., weird types).
