This generic implementation is meant to define once and for all
all the logic common to all implementations of the LLL upon any platform.
It goal of this Subproject is a define and implement
a low-level language that will fulfill all the requirement
to be used as a basis for the Tunes system,
including self-extending into the full Tunes HLL, etc.
A first, original version should be written using widely
available existing tools, and not bother about speed efficiency of
generated code. It can use dirty hacks of all kinds.
The definitive version will be written using the own Tunes
language system; it will be as clean as can be, and rely on all our usual
Tunes tools to produce
"optimized" code (oh I hate this
word).
It should map as well as possible our current targets as well as
future ones.
