Josh Stone 8964eb9887 Chop the tests up
The test modules were getting huge, and some of its functions were
actually a huge amount of code due to macros, causing tests to take a
long time just to compile.  They are now separated into a few different
tests, and the scalar macros especially are now expanded more sparingly
in just a few `check()` functions.

Test compile times for me went from about 25 seconds to 1.5s in debug
mode, and from 300 seconds (!) to about 8s in release mode.
