lit is picking up a stale executable in the unittests tree, which is
failing on Windows.
To simplify the CMake and avoid problems like this in the future, now we
always compile the test, but the test exits successfully when plugins
are not enabled.

Summary:
Currently the PluginsTests.LoadPlugin unit test is failing in
LLVM configurations that have LLVM_EXPORT_SYMBOLS_FOR_PLUGINS enabled
because the EnableABIBreakingChecks symbol is missing.
This patch fixes the issue by linking some additional libraries to the
test plugin if LLVM_EXPORT_SYMBOLS_FOR_PLUGINS is enabled.

Summary:
Add a new plugin API. This closes the gap between pass registration and out-of-tree passes for the new PassManager.
Unlike with the existing API, interaction with a plugin is always
initiated from the tools perspective. I.e., when a plugin is loaded, it
resolves and calls a well-known symbol `llvmGetPassPluginInfo` to obtain
details about the plugin. The fundamental motivation is to get rid of as
many global constructors as possible. The API exposed by the plugin
info is kept intentionally minimal.
