The assembly optimizations were making unsafe assumptions about which address
spaces had which identifiers.
Also, fix vload/vstore with 64-bit pointers. This was broken previously on
Radeon SI.
This version still only has assembly versions of int/uint 2/4/8/16 for global
loads and stores on R600, but it does it in a way that would be very easily
extended to private/local/constant and could also be handled easily on other
architectures.
v2: 1) Leave v[load|store]_impl.ll in generic/lib
2) Remove vload_if.ll and vstore_if.ll interfaces
3) Fix address+offset calculations
3) Remove offset from assembly arg list

The assembly should be generic, but at least currently R600 only supports
32-bit stores of [u]int1/4, and I believe that only global is well-supported.
R600 lowers the 8/16 component stores to multiple 4-component stores.
The unoptimized C versions of the other stuff is left in place.
