R600/SI: Add support for buffer stores v2 v2: - Use the ADDR64 bit Reviewed-by: Christian König <christian.koenig@amd.com> llvm-svn: 178931

R600: Use EXPORT_RAT_INST_STORE_DWORD for stores on Cayman We were using RAT_INST_STORE_RAW, which seemed to work, but the docs say this instruction doesn't exist for Cayman, so it's probably safer to use a documented instruction instead.

; The stores in this function are combined by the optimizer to create a
; 64-bit store with 32-bit alignment. This is legal for SI and the legalizer
; should not try to split the 64-bit store back into 2 32-bit stores.
;
; Evergreen / Northern Islands don't support 64-bit stores yet, so there should
; be two 32-bit stores.
