Summary: Currently in OpenMPOpt we strip `noinline` attributes from runtime functions. This is here because the device bitcode library that we link has problems with needed definitions getting prematurely optimized out. This is only necessary for OpenMP offloading to GPUs so we should narrow the scope for where we spend time doing this. In the future this shouldn't be necessary as we move to using a linked library rather than pulling in a bitcode library in Clang.
