This patch add new environment variables to control compiler cache. Works as follow: If persistent cache is set driver check if NEO_CACHE_DIR is set. If not then driver checks XDG_CACHE_HOME - If exists then driver create neo_compiler_cache folder, if not then driver checks HOME directory. If each NEO_CACHE_DIR, XDG_CACHE_HOME and HOME are not set then compiler cache is disabled. Current support is for Linux only.
