[llvm] [llvm] Use llvm::equal (NFC) (PR #169173)

[Kazu Hirata via llvm-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/169173

While I am at it, this patch uses const l-value references for
std::shared_ptr.  We don't need to increment the reference count by
passing std::shared_ptr by value.

Identified with llvm-use-ranges.
