    Both of these functions fail in different places:

```
; RUN: llc -mtriple=amdgcn-amd-amdhsa -mcpu=gfx900 < %s

define void @store_null_null_use_buffer_fat_ptr() {
  store i32 0, ptr addrspace(7) null, align 4
  ret void
}

define void @store_null_buffer_resource() {
 store i32 0, ptr addrspace(8) null, align 4
  ret void
}
```

The first one fails trying to use a non-integer type in getConstant, the second fails in the legalizer
