The clang compiler prepends the HIP header include paths to the search list using -internal-isystem when building for the HIP language. This prevents warnings related to things like reserved identifiers when including the HIP headers even when ROCm is installed in a non-system directory, such as /opt/rocm. However, when HIP is installed in /usr, then the prepended include path would be /usr/include. That is a problem, because the C standard library headers are stored in /usr/include and the C++ standard library headers must come before the C library headers in the search path list (because the C++ standard library headers use #include_next to include the C standard library headers). While the HIP wrapper headers _do_ need to be earlier in the search than the C++ headers, those headers get their own subdirectory and their own explicit -internal-isystem argument. This include path is for <hip/hip_runtime_api.h> and <hip/hip_runtime.h>, which do not require a particular search ordering with respect to the C or C++ headers. Thus, HIP include path is added after other system include paths. With contribution from Cordell Bloor. Reviewed by: Artem Belevich Differential Revision: https://reviews.llvm.org/D120132
