By "large tests", I assume you mean the .ll tests?  Those are
one-file-per-test.  Also, if you use Chris' suggestion on directories, it
will separate the unit tests from the large tests.

Yes, I agree, they'll link faster if we have fewer tests.  I would not want
a single massive test for all of LLVM -- how about 1 test binary per major
directory in llvm/lib, unless it's really necessary to split them up, e.g.
target-dependent unittests, but each .cpp file would ideally have its own
_test.cpp file, so it's easier to keep the tests for different modules
separate.
