Remove LIT< in favor of LIT" exclusively This duplicated feature existed because of bootstrapping issues with LIT", but again, with careful threading, we can clean things up. We can now have a proper "Collapse OS" prompt :)

Move Cross-compiled core from B390 to B350 and renamed it "Core words". Also, reworded the presentation.

De-stabilize (br), (?br), (loop), (s) When writing the xcomp documentation, I realized that with careful threading and by accepting a bit of code duplication in the xcomp toolset, I could de-stabilize a couple of words. (n) and EXIT are a bit trickier, but I think it can be done. It would be nice to get rid of stable wordrefs...

Remove LITA It was useful when we still had the relinker, but now it has no use. I was waiting a bit to see if the distinction would be useful again, but it seems like it won't.

Refer to stable wordref by direct offset in "hot zone" immediates Previously, it was impossible to cross-compile Collapse OS from a binary-offsetted Collapse OS because stable ABI wordrefs would have a wrongly offsetted address. This solves the problem by replacing those wordrefs by direct, hardcoded stable ABI offset references.
