Reorganize build system to minimize duplication while handling 3
scenarios:
1. Locally running tests with `mu test`
2. Locally running tests until some layer with `build_and_test_until`
3. Running on Linux with `test_layers`
4. Running on Travis CI with multiple sharded calls to `test_layers`
One thing we drop at this point is support for OSX in test_layers. We
don't need it now that we have Travis CI working.
Since I switched to a Mac laptop (commit 2725) I've been lax in running
test_all_layers because I have to ssh into a server and whatnot. I
should just get CI setup somewhere..
Make it easy to skip distracting valgrind errors when debugging more
obvious errors in early layers. Just throw a 'test' at the end of
build_and_test_until commands to not run valgrind (and make it a regular
test run).
Region to click on to edit is now reduced to just the menu bar for the
sandbox (excluding the 'x' for deleting the sandbox). The symmetry there
might be useful, but we'll see if the relative click area is
in line with how commonly the actions are performed.
All primitives now always write to all their products. If a product is
not used that's fine, but if an instruction seems to expect too many
products mu will complain.
In the process, many primitives can operate on more than two ingredients
where it seems intuitive. You can add or divide more than two numbers
together, copy or negate multiple corresponding locations, etc.
There's one remaining bit of ugliness. Some instructions like
get/get-address, index/index-address, wait-for-location, these can
unnecessarily load values from memory when they don't need to.
Useful vim commands:
%s/ingredients\[\([^\]]*\)\]/ingredients.at(\1)/gc
%s/products\[\([^\]]*\)\]/products.at(\1)/gc
.,$s/\[\(.\)]/.at(\1)/gc
