ARM: do not add a regmask for TAILJUMPs The jump doesn't really kill the registers, the following call does but we never get back anyway. This avoids some verify-machineinstrs problems when TAILJUMPs are if-converted. llvm-svn: 191962

Similar migration script can be used to update test cases, which successfully migrated all of LLVM and Polly, but about 4 test cases needed manually changes in Clang.
