float: Disable `total_cmp` sNaN tests for `f16`
There is an LLVM bug with lowering of basic `f16` operations that mean a round trip via `__extendhfsf2` and `__truncsfhf2` may happen for simple `abs` calls or bitcasts [1]. This is problematic because the round trip quiets signaling NaNs. For most operations this is acceptable, but it is causing `total_cmp` tests to fail unless optimizations are enabled. Disable `total_cmp` tests involving signaling NaNs until this issue is resolved.
