read_frame_register_value and big endian arches

The read_frame_register_value function as it was implemented introduced
a regression on big-endian targets. The problem appears when trying to
get the value of an entity stored inside a register, and when the size
of the entity is smaller than the size of the register. In that case,
we were always reading the first N bytes of the register, which is wrong
for big-endian architectures, where we need to read the last N bytes of
the register.

gdb/ChangeLog:

        * findvar.c (read_frame_register_value): Read correct bytes from
        register on big-endian architectures.

They just never trigger.

The problem comes from the fact that we always set the debug registers
to zero, no matter what.  This in turn comes from the fact that we
use i386_low_insert_watchpoint to compute the DR values:

      return i386_low_insert_watchpoint (&debug_reg_state,
                                         type, addr, len);

This function saves the new values in debug_reg_state.  However,
the values we actually use when setting the DR registers are
taken from two different globals:

        static unsigned dr_status_mirror;
        static unsigned dr_control_mirror;

These are really never actually changed (their value is set from
the DR values read from the inferior, but since we never change
them, in practice, they never change).

The fix is to use the values provided by debug_reg_state, and
to eliminate the two dr_[...] globals.

gdb/gdbserver/ChangeLog:

        * win32-i386-low.c (dr_status_mirror, dr_control_mirror): Delete.
        (i386_dr_low_get_control, i386_dr_low_get_status): Use
        dr_status_mirror and dr_control_mirror from debug_reg_state.
        (i386_dr_low_get_status): Use debug_reg_state.dr_status_mirror
        (i386_initial_stuff): Remove use of deleted globals.
        (i386_get_thread_context, i386_set_thread_context,
        i386_thread_added): Use dr_status_mirror and dr_control_mirror
        from debug_reg_state.
