Implement fshr/fshl intrinsics
Changes: - IntrinsicCleaner accepts fshr/fshl as accepted intrinsics - Executor::executeCall converts fshr/fshl to urem/zext/concat/shift/extract - Klee/main suppresses warnings about externals that are LLVM reserved (i.e., begin with "llvm.") - New test exercises 32 and 7 bit versions including oversize shift values Test values are based on LLVM's test for fshl/fshr - Changes that depend on existence of fshr/fshl are guarded by #if LLVM_VERSION_CODE >= LLVM_VERSION(7, 0) or ; REQUIRES: geq-llvm-7.0
