The "noduplicate" function attribute exists to prevent certain optimizations from duplicating calls to the function. This is important on platforms where certain function call duplications are unsafe (for example execution barriers for CUDA and OpenCL). This patch makes it possible to specify intrinsics as "noduplicate" and translates that to the appropriate function attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204200 91177308-0d34-0410-b5e6-96231b3b80d8
