syntax/parse: speed up "is literal bound?" check
...
Can't do check completely statically, because phase of comparison
is expression (and even default is slightly unpredictable).
So instead compute whether check would succeed for likely phase
offsets, and use list of ok offsets as run-time fast path (memv
instead of identifier-binding).

I believe this fixes PR12117. The teaching languages rely on syntax/struct. (I have run the teaching language tests, but do not other uses of syntax/struct.) It appears that syntax/struct has been incorrectly creating this information for some time. The problem is that it would end the static info with a #f if the selectors or setters were omitted, but reading the documentation implies that there should be a final #f in either case. I've therefore changed the boolean to an or over the flags
