4262178cf5 Document the git clone --recurse-submodules requirement. 
Currently, it's necessary to do this in order to obtain a lightbeam
checkout, in order to build wasmtime.

I'm very interested in learning about better ways to solve this problem.

30dcf4aed6 Lightbeam requires nightly, so don't use cargo test --all. 
For now, test all non-nightly-only packages individually, rather than
using cargo test --all. Lightbeam's tests are run separately if nightly
is available.

cd8a42e01f Fix #686: Allow code shrink in relaxation if the shrinking pass hasn't been run; 
Also:
- make sure to apply diversions when determining offsets for code
relaxation.
- select the smallest encoding when selecting a relaxed branch
instruction.

2dd1552369 [meta] Make Typevar::type_set private, and add a second getter to read it directly; 
There might be a silent bug in the Python module which directly reads
from this type_set field; in particular, it does so when reading all
controlling type variables, which all seem to be free variables (i.e. no
parent typevar). So imitate this behavior here, until we're sure there
are no other meta generators that rely on this.

5edee84f67 [meta] Port TypeVar's test_functions to Rust; 
Fixes two issues:

- name of derived type variables wasn't correct. (This is used during
code generation.)
- the TypeVar::derived() function wasn't creating the correct type set
(and would instead propagate the parent's one).
