<pre>llvm::UpgradeIntrinsicCall() function in lib/IR/AutoUpgrade.cpp source file
checks if the IR includes an old intrinsic and replaces it with the upgraded
IR.
The checks are implemented by a long "if else" sequence which some compilers
complain about when it gets too long (For example, Microsoft C++ compiler will
accept up to 127 if-else statements).
A refactoring to this "structure" should be considered as an effort to reduce
the use of llvm x86 specific intrinsics is being initiated, and as a result
many new cases will be added to the same control flow in the future.</pre>
