Support the new LLVM pass manager

The legacy pass manager is deprecated in LLVM 13 [0], and will be
removed entirely by LLVM 16. We should use the new pass manager [1] when
building with a recent version of LLVM.

Since we still use LLVM 10 by default, we need two code paths for now.

Note that this change illustrates that LLVMReactor.cpp still has some
dependencies on the guts of LLVM, that belong in LLVMJIT.cpp instead.
This will be cleaned up in a subsequent change. This one is based
directly on cl/442613159 which was authored by aeubanks@.
