Subject: [PATCH] Add minor version to libclang.so and libclang-cpp.so SONAME
This patch is for the release/11.x branch. We need to bump the SONAME, because
the ABI of the shared library is changing

commit 9bbcb554cdbf1a7b85e9a72169e4037cf4736a10
Author: Marco Antognini <marco.antognini@arm.com>
Date: Thu Oct 29 10:30:11 2020 +0000
Address ABI issues introduced with CXCursor_CXXAddrspaceCastExpr
Revert values in CXCursorKind as they were before
CXCursor_CXXAddrspaceCastExpr was introduced in a6a237f2046a ([OpenCL]
Added addrspace_cast operator in C++ mode., 2020-05-18).
Insert CXCursor_CXXAddrspaceCastExpr after the last expression in
CXCursorKind using the next available value.
