By doing something like calling read rather than read-positioning-symbols
from the byte compiler, and putting conditional compilation into
lisp_h_EQ, etc., in src/lisp.h?  This would leave the compiler not fully
functional, of course.  It might work.

I get the feeling it's one of those things which sounds simple, but there
might be unforeseen problems waiting.  One of those problems might be the
option somehow surviving long beyond its intended lifetime, with pressure
to maintain it coming from somewhere.

I would more favour the slightly more laborious strategy: benchmark on
the master branch in two repositories, one just before the big merge, the
other just after.
