Harold,

Thank you for doing this fastidious renaming work a second time.
Overall it looks good and new names sound explicit to me.

Looks good to me.

FlatArrayFlatten is not very explicit.
What about UseFlatArray?

Shouldn't is_value_array_klass() be is_flat_array_klass()?

InlineArrayElementMaxFlatSize -> FlatArrayElementMaxSize ?
