73e44d8ae4 R600/SI: Report unaligned memory accesses as legal for > 32-bit types
In reality, some unaligned memory accesses are legal for 32-bit types and
smaller too, but it all depends on the address space.  Allowing
unaligned loads/stores for > 32-bit types is mainly to prevent the
legalizer from splitting one load into multiple loads of smaller types.

4efccd0fb1 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.
