So going back to my IBM128 build, I see that libphobos does have some code
relating to mant_dig == 106 which is IBM128/IBM double-double, including in the
file that's ICEing here due to the assert. I've patched two asserts to allow
IBM128 and I'm re-kicking off a bootstrap and regtest. It might be that the
only problem the asserts needed updating? We'll see.
