AMDGPU: Add intrinsics for sin/cos These provide direct access to the hardware instruction without the unit version required like llvm.sin/llvm.cos lowering requires. llvm-svn: 260782

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
