[llvm] [LTO] Remove extraneous ArrayRef (NFC) (PR #90306)

[Kazu Hirata via llvm-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/90306

We don't need to explicitly create these instances of ArrayRef because
Hasher::update takes ArrayRef, and ArrayRef can be implicitly
constructed from C arrays.
