[CIR][Pipeline] Support -fclangir-analysis-only #638

Closed ChuanqiXu9 closed 1 month ago

ChuanqiXu9 commented 1 month ago

Close https://github.com/llvm/clangir/issues/633.

This patch introduces -fclangir-analysis-only option to allow the users to consume the AST to the CIR (and potential analysis passes, this can be done by specifying -Xclang -fclangir-lifetime-check="" now or some default value in following patches) and also generating the LLVM IR by the traditional code gen path. This will be helpful to use CIR with real world projects without worrying the correctness and completeness of CIR CodeGen part.

I'll merge as soon as the conflicts are fixed.

It conflicts with something that landed more or less about the time you updated, shall work if you do it again.
