ARM: use LLVM IR to represent the vshrn operation vshrn is just the combination of a right shift and a truncate (and the limits on the immediate value actually mean the signedness of the shift doesn't matter). Using that representation allows us to get rid of an ARM-specific intrinsic, share more code with AArch64 and hopefully get better code out of the mid-end optimisers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201085 91177308-0d34-0410-b5e6-96231b3b80d8
