ARM: use vqdmull and vqadds/vqsubs to implement vqdmlal/vqdmlsl The NEON intrinsics vqdmlal and vqdmlsl are really just combinations of a saturating-doubling-multiply (vqdmull) and a saturating add/sub, so now that LLVM can spot those patterns Clang should emit them instead of specialised intrinsics. Feature already tested by existing ARM NEON intrinsics tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@189462 91177308-0d34-0410-b5e6-96231b3b80d8
