OK, after another round of renaming:
- "is_inline_type" is used to test if the type of a field is an inline type or not
- "is_inlined" is used to test if the field has been flattened in the layout of its container
Both expression are close, and can easily be found together with grep.
I've tried to fix all the comments to align them with the new names of methods and fields.
The term "flattened" is still use for arrays.
