This commit is removing the last pieces of AnalysisWrapper.cpp (including the ExternalFunctionsPassedConstants pass, aka print-externalfnconstants). The pass only existed for the legacy PM, and it was not regression tested. And since the pass did not force the use of the legacy pass manager there was no simply way to run the pass nowadays, at least not by using opt.

The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
