First round of updates in response to commenting out stale expectations.

First round of updates in response to commenting out stale expectations.

This deletes a few tests which sound like they're wrong/buggy, and requests
rebaselines for a variety of others (or marks them expected-to-fail for
reftests).  It also restores the stale expectations for a few tests where that's
the most appropriate action.

Just FYI, the canvas/philip tests are imported from an upstream test suite, so
the deleted tests may reappear when we update our copy of that suite.

Yeah, I checked with dpranke before this because I was worried about precisely
that; he said to go ahead and delete these, and that we were unlikely to update
our copy again anyway.  (The README says that suite was last updated in 2010,
IIRC.)

I'm sure if we ever do re-update we'll see that the test fails (if applicable)
at the time that happens.
