Add support for constant struct member field offsets.

* loc2c.h (c_translate_add_offset): New function prototype.
* loc2c.c (c_translate_add_offset): New function implementation.
* loc2c-test.c (handle_variable): Use c_translate_add_offset if appropriate.
* dwflpp.cxx (translate_location): Likewise.
