AMDGPU: Remove legacy rsq.clamped intrinsic Mesa still has a use of llvm.AMDGPU.rsq.f64 remaining. Also fix mismatch with non-IEEE rsq selecting to IEEE rsq. llvm-svn: 275617

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel Currently the default C calling convention functions are treated the same as compute kernels. Make this explicit so the default calling convention can be changed to a non-kernel. Converted with perl -pi -e 's/define void/define amdgpu_kernel void/' on the relevant test directories (and undoing in one place that actually wanted a non-kernel). llvm-svn: 298444
