  -----------
  Clean up t/dynpmc/gziphandle.t stream tests

* The two throws_substring tests had nothing to do with the rest of
  the tests in that function.  Split them out into another function.

* Make some test messages clearer.

* Include comments for non-test portions.

* Use variable names so new developers don't have to remember what
  registers are for.

* Fudge by 1 byte for problematic zlib version on OS X
