Summary: Update to clang-15 compiler and libraries as clang-12 is ancient. The changes to oilgen are necessary because the new internal toolchain is being more picky about linking PIC to PIC. In certain modes we build with PIC, but try to link a non-PIC oilgen artifact. Add the ability to build the oilgen artifacts with PIC which sorts this.
