This trades off more compile time for less peak memory usage.

With the option turned on:
https://llvm-compile-time-tracker.com/compare.php?from=1fb24fe85a19ae71b00875ff6c96ef1831dcf7e3&to=f1604149f211f2fa2f5609ccdebb96491e961b7f

For now this is just experimental.

See comments on why this may affect optimizations.
