[llvm] [AMDGPU] Remove some invalid tests (PR #98796)

So if you run `llc -run-pass=XXX -early-live-intervals` then the `-early-live-intervals` option has no effect?

Patch LGTM. But I see two more tests that should also be updated:
```
test/CodeGen/AMDGPU/gfx10-twoaddr-fma.mir
test/CodeGen/AMDGPU/twoaddr-fma-f64.mir
```
