Moritz Bunkus c9884c3e77 build system: don't optimize when compiling iso639_language_list.cpp ... Even `-O1` causes compilation time & memory usage to skyrocket, possibly exponentially, with the number of entries to `emplace_back()` into the vector. This isn't so bad with the current number of entries (489). In that case compilation with `-O3` only takes 7.2s. However, extending the list to cover ISO 639-3 means that the list will include 7160 entries. With that many entries things are much, much more severe: • with `-O1` alone compilation takes 11m 23s already. • with `-O3` memory usage exceeded 20 GB after six minutes when I had to abort due to other running applications getting killed. Runtime cost is negligible. I ran a micro benchmark. With all 7160 entries and no optimizations (`-O0`) the initialization takes ~1.4 milliseconds for the one-time initialization on startup; with optimizations (`-O1`) it still took ~570 microseconds. Part of the implementation of #3007.		2021-02-17 22:18:20 +01:00
