* include/std/std_fstream.h (_M_is_indeterminate): Remove.
* src/fstream.cc
(basic_filebuf<char/wchar_t>::_M_underflow): Simplify: either
there is no buffer or __testget == !__testinit.
* src/fstream.cc
(basic_filebuf<char/wchar_t>::_M_underflow): _M_set_determinate()
automatically sets, if appropriate, _M_out_cur == _M_in_cur.
* include/std/std_fstream.h (_M_destroy_pback): Don't set
unnecessarily _M_pback_cur_save and _M_pback_end_save.
* include/std/std_fstream.h (_M_set_determinate): Minor tweak.
* include/std/std_sstream.h (_M_sync): Minor tweak.
* include/bits/fstream.tcc (close): No need to call
_M_destroy_pback, setting _M_pback_init to false suffices
to clean up.

* unwind-dw2.c (uw_update_context_1): Only set cfa as sp if
previous frame didn't save sp. Clear sp for next frame.

mips_set_frame_expr.
