Fixes for many low-severity compiler warnings (#576)

* Fixes for many low-severity compiler warnings

Mostly a lot of pedantic things like end-of-file newlines and commas on the last enum value.  However some fixes like the weak v-tables warnings fixes might help with code gen.  It's unclear if the linker is able to elide multiple copies of the same type's v-table in different translation units, (sometimes it can) but these fixes ensure we don't have to rely on it.
