Split instruction and immediate stream

There was a recent post to the gcc mailing list which showed
interesting concept of dealing with large constants in an ISA:
Splitting a the instruction and constant stream.  It can be found
at https://github.com/michaeljclark/glyph/ , and is named "glyph".

I think the problem the author is trying to solve is better addressed by
My 66000 (and I would absolutely _hate_ to write an assembler for it).
Still, I thought it worth mentioning.
