merge-functions pass

Merge similar functions that only differs constant values (like immediate operand of const and call insts) by parameterization. Performing this pass at post-link time can merge more functions across objects. Inspired by Swift compiler's optimization which is derived from LLVM's one: https://github.com/apple/swift/blob/main/lib/LLVMPasses/LLVMMergeFunctions.cpp https://github.com/llvm/llvm-project/blob/main/llvm/docs/MergeFunctions.rst
