a branch to try to help the jit reason about nested scopes better, Cells in

start implementing Cell families, that Cells are grouped into, according to
their outer defining function. Goal is to be able to track immutability of
Cells (like mapdict instance fields).

Doesn't work so far, since the initializing set is counted as a mutation so
far.

fix the failing test: do the cell initialization differently, first initialize
only those cells that aren't arguments. After argument parsing, create the
cells with the correct values directly. That way the tracking whether cells are
ever mutated works correctly for arguments.

fix bug

(also, it helps to add the test file)

fix test, this test shows the effect of the branch: global immutable cells can
have their access completely folded away

make the cells optimization also work for non-arguments, as long as the
variable is only written to once

undo most of d2497f614daa: simplify Cell initialization back to what it was on
default, now that Cell change tracking is somewhat more robust

merge nested-scopes-jit

teach the JIT to reason better about nested scopes. In particular, track
whether the cells of a single local variable are ever mutated, and if they
aren't, constant fold the read access from them, if they are constant.
