[llvm] [AMDGPU] Clear load addresses between functions (PR #102515)

[Alexis Engelke via llvm-commits]

https://github.com/aengelke created https://github.com/llvm/llvm-project/pull/102515

SLoadAddresses previously held data across different functions and used these for dominance queries of blocks in different functions. This is not intended; clear the state at the end of the pass.
