clang-format alltests.js.
clang-format alltests.js.

Rationale:

1) It's easier to read. When I was mucking with alltests.js for external
testing, the monolothic single line was very hard to deal with.
2) Running clang-format over just formatting appropriately in genalltests.sh is future
proof to clang changes.
3) This file will be subject to the internal and external clang checks. Might
as well just format it instead of ignoring it.
