Alessandro Di Federico 8deab9c7ea Whitespace and other minor changes
* Drop unused argument names from function prototypes
* Make `static` some methods
* Disable some copy constructors
* Fix casing of Doxygen `\file` directives
* Add some casts to make the compiler happy
* Initialize `hasRelocationAddend` for AArch64
* Use references in range-for where possible
* Drop default for `switch` statements covering all the entries of an `enum`
* Make some global variables `static`
* Drop dead functions
