We made a little change on the patch which comes from upstream, as follows.

- patch: 0004-llvmGen-Introduce-infrastructure-for-module-flag-metadata.patch
Cherry-pick from upstream with little change.
The corresponding upstream commit is: a6a3874276ced1b037365c059dcd0a758e813a5b
Role: required to add a moduleflag to the llvm IR.
NOTE: We made a little change on the upstream patch because we have to: without the change, a large number of patches would need to be backported to ghc-9.6.6 so that the upstream patch(a6a3874276ced1b037365c059dcd0a758e813a5b) could be backported to ghc-9.6.6, and one of these would break the public interface, i.e., the stack alignment ghc option would be removed. We don't want that happen, so we have to made the change on the upstream patch.
