Subject: Remove abi_revision handling


We now longer ship rcs outside of copr, so this is no needed anymore.

-Subject: [PATCH] cmake: Allow shared libraries to customize the soname using
- LLVM_ABI_REVISION
-
-The LLVM_ABI_REVISION variable is intended to be used for release
-candidates which introduce an ABI change to a shared library.  This
-variable can be specified per library, so there is not one global value
-for all of LLVM.
-
-For example, if we LLVM X.0.0-rc2 introduces an ABI change for a library
-compared with LLVM X.0.0-rc1, then the LLVM_ABI_REVISION number for
-library will be incremented by 1.
-
-In the main branch, LLVM_ABI_REVISION should always be 0, it is only
-meant to be used in the release branch.
-
-Differential Revision: https://reviews.llvm.org/D105594
