[llvm] Fix warnings while compiling SLPVectorizer.cpp (PR #118051)

[Anutosh Bhat via llvm-commits]

https://github.com/anutosh491 created https://github.com/llvm/llvm-project/pull/118051

Towards #118048

I was building llvm (clang and lld) for webassembly and came across these warnings. Not sure if they are seen in our builds too. This PR tries to address those warnings.
