[AMDGPU] Update test nullptr.ll to use amdgiz environment

[yaxunl]

Summary

This test needs to be manually updated since it is difficult to do it with script.

Addr space 6 to 23 are only used by r600, therefore only check them for r600.

[arsenm]

Changing the size of the other address spaces seems like a problem, but I'm not sure what they are for. If we actually care about them, they need to be added to the datalayout

It seems the backend uses these address spaces. I will update the datalayout instead.

Actually addrspace 6 to 23 are only used by r600. I will add separate run line for amdgcn and r600.

[yaxunl]

Add run line for r600.
