Correct AMDGPU strictfp tests to follow the rules documented in the LangRef: https://llvm.org/docs/LangRef.html#constrained-floating-point-intrinsics Mostly these tests just needed the strictfp attribute on function definitions. I've also removed the strictfp attribute from uses of the constrained intrinsics because it comes by default since D154991, but I only did this in tests I was changing anyway. I also removed attributes added to declare lines of intrinsics. The attributes of intrinsics cannot be changed in a test so I eliminated attempts to do so. Test changes verified with D146845.
