[PR tui/14880] Fetch values before comparing their contents.

PR tui/14880 shows a reproducer that triggers this assertion:

  int
  value_available_contents_eq (const struct value *val1, int offset1,
  			     const struct value *val2, int offset2,
  			     int length)
  {
    int idx1 = 0, idx2 = 0;

    /* This routine is used by printing routines, where we should
       already have read the value.  Note that we only know whether a
       value chunk is available if we've tried to read it.  */
    gdb_assert (!val1->lazy && !val2->lazy);

The fix is to fetch the value before comparing the contents.  The
comment additions to value.h explain why it can't be
value_available_contents_eq itself that fetches the contents.

Tested on x86_64 Fedora 17.
