In commit 8514ee9b31 (HIP: analyze output of `hipcc` to determine
default GPU architecture, 2021-05-27, v3.21.0-rc1~66^2) we dropped these
from most tests, but missed `HIP.TryCompile`. Since commit 735f41fc2d
(HIP: Use 'rocm_agent_enumerator' to determine CMAKE_HIP_ARCHITECTURES,
2021-09-15, v3.21.3~1^2~3) we automatically select architectures anyway.
