Inline initialization of gdbarch members 

This changes gdbarch to use the "predefault" to initialize its members
inline.  This required changing a couple of the Value instantiations
to avoid a use of "gdbarch" during initialization, but on the whole I
think this is better -- it removes a hidden ordering dependency.
