One way to allow using a single IPA with multiple pipelines would be to allow the IPA to declare itself compatible with more than one pipeline, turning ipaModuleInfo.pipelineName[] into e.g. a vector. But the way ipaModuleInfo is loaded as an ELF symbol requires it to be a simple flat C-struct. Instead, move the IPA creation procedure to be name-based, introducing an overload to IPAManager::createIPA(pipe, name, minVer, maxVer) that allows to specify the name of the IPA module to match. Pipeline handlers that wants to use their name as matching criteria can continue doing so using the already existing createIPA(pipe, minVer, maxVer) overload.
