This make inclusion of unicode-inl.h in object.h absolete. Now most compilation units don't require that header. It also breaks a cycle within declarations of the scanner.h header. This tries to remove includes of "-inl.h" headers from normal ".h" headers, thereby reducing the chance of any cyclic dependencies and decreasing the average size of our compilation units. Note that this change still leaves 3 violations of that rule in the code, checked with the "tools/check-inline-includes.sh" tool.
