CYGWIN uses the same format of WIN32 for shared libraries.
As the comment says: "a shared library can't have undefined references", in this case CYGWIN must be handled like WIN32 by CMakeLists.txt, otherwise you will get several errors when linking because some symbols are undefined.
Attached patch fixes this issue and allows to complete the build process for those targets.

This is part of effort in removing -enable-new-pm flag.
As a prat of this effort one of example passes SimplifyCFG must
be ported to new PM which will allow to remove the flag
calls from the tests that are using this pass.

This patch adds a new IRTransformations directory to llvm/examples/. This is
intended to serve as a new home for example transformations/analysis
code used by various tutorials.
If LLVM_BUILD_EXAMPLES is enabled, the ExamplesIRTransforms library is
linked into the opt binary and the example passes become available.
To start off with, it contains the CFG simplifications used in the IR
part of the 'Getting Started With LLVM: Basics' tutorial at the US LLVM
Developers Meeting 2019.
