radeon/ac: use ds_swizzle for derivs on si/cik.
This looks like it's supported since llvm 3.9 at least,
so switch over radeonsi and radv to using it, -pro also
uses this. We can now drop creating lds for these operations
as the ds_swizzle operation doesn't actually write to lds at all.
Acked-by: Marek Olšák <[email protected]>
(stable requested due to fixing radv CIK conformance tests)
