Invoke OptimizerLastEPCallbacks in PreLinkThinLTO #69665

  1. Invoke OptimizerLastEPCallbacks in PreLinkThinLTO 

    The default ThinLTO pre-link pipeline does not include optimizer last
extension points. Thus, when using the new LLVM pass manager & ThinLTO
& sanitizers on any opt-level different from zero, the sanitizer
function passes would be omitted from the pipeline.

Add optimizer last extensions points manually to the pipeline, but guard
registration with stage check in the case this behaviour changes in the
future.

  2. Add test for -Znew-llvm-pass-manager -Clto=thin -Zsanitizer=... 

    Additionally verify that the current implementation of LLVM version
check (which uses lexicographic ordering) is good enough to exclude
versions before LLVM 9, where the new LLVM pass manager is unsupported.
