[clang][CodeGen] Use llvm::stable_sort for multi version resolver options
The use of llvm::sort causes periodic failures on the bot with EXPENSIVE_CHECKS enabled,
as the regular sort pre-shuffles the array in the expensive checks mode, leading to a
non-deterministic test result which causes the CodeGenCXX/attr-cpuspecific-outoflinedefs.cpp
testcase to fail on the bot (http://lab.llvm.org:8080/green/job/clang-stage1-cmake-RA-expensive/).
