ELF-based platforms currently support defining multiple static initializer table sections with differing priorities, for example `.init_array.0` or `.init_array.100`; the default `.init_array` corresponds to a priority of 65535. When building a shared library or executable, the system linker normally sorts these sections and combines them into a single `.init_array` section. This change adds the capability to recognize ELF static initializers with priorities other than the default, and to properly sort them by priority, to Orc and the Orc runtime.
