This test has incorrect layout (should be one-folder deeper) so it is never run. I moved it to the spread plugin.

This test is split to two tests because the former will be optimized but not the latter, which is very confusing.

The inferrer is used by the spread transform and for-of transform to determine whether the argument / rhs is an array from its type annotations or static structure. This PR begins by adding TS tests to the inferrer and fixing bugs caught by the new test.
