Use allocate_optimized_out_value instead of set_value_optimized_out.
Allocate the value as optimized out from the start rather than allocating
a value with contents, and then marking it optimized out.

2013-07-04 Pedro Alves <palves@redhat.com>
* findvar.c (value_of_register): Use allocate_optimized_out_value
if the register has been optimized out, instead of
set_value_optimized_out.
* frame-unwind.c (frame_unwind_got_optimized): Use
allocate_optimized_out_value.
