* c-common.c (c_common_nodes_and_builtins): The first parameter to
__builtin_va_start and __builtin_va_copy is now either a 'va_list'
or a reference to a va_list.
* builtins.c (stabilize_va_list): Simplify now we don't have to
work around C array address decay.
* c-typeck.c (convert_for_assignment): Handle assignment to
a reference parameter by taking the address of the RHS.
* ginclude/stdarg.h (va_start): Don't take address of first parameter.
(va_copy): Likewise.
(__va_copy): Likewise.
* ginclude/varargs.h (va_start): Likewise.
(__va_copy): Likewise.
