Arseny Kapoulkine 094a0c8ebe tests: Add compact hash table reserve test
This makes sure all .reserve calls failure paths are covered. These
tests don't explicitly test if reserve is present on all paths - this is
much harder to test since not all modifications require reserve to be
called, so we'll have to rely on a combination of automated testing and
sanity checking for this.

Also add more parsing out of memory coverage tests.
