Reorganized zen make_defs.mk to mimic zen2, zen3.
Details: - Restructured clang and AOCC support in config/zen/make_defs.mk to bring that file into alignment with recent changes to the make_defs.mk of zen2 and zen3 subconfigs. - Added missing options (-mllvm -disable-licm-vrp) to the znver1 conditional case of aocc handling in zen2/make_defs.mk. These options were present in the amd_config.mk fragment that was being included in the previous version of zen2/make_defs.mk, but was accidentally omitted from the newer version introduced recently in 7872c3a.
