This is one of the first steps at moving to replace target-dependent
intrinsics with target-indepdent intrinsics. The first instruction(s) to be handled are the vector versions of count leading zeros (ctlz). The changes here are to clang so that it generates a target independent vector ctlz when it sees an ARM dependent vector ctlz. The changes in llvm are to match the target independent vector ctlz and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector ctlzs with target-independent ctlzs. There are also changes to an existing test case in llvm for ARM vector count instructions and a new test for the bitcode upgrade. <rdar://problem/11831778> There is deliberately no test for the change to clang, as so far as I know, no consensus has been reached regarding how to test neon instructions in clang; q.v. <rdar://problem/8762292> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160200 91177308-0d34-0410-b5e6-96231b3b80d8
