libstdc++/5045
* include/bits/std_limits.h (defines, numeric_limits<bool>::digits10):
Fix digits10 values for integral types.
* include/bits/locale_facets.tcc (num_get::do_get for integral types):
Tweak _M_extract_int call.
* testsuite/27_io/istream_extractor_arith.cc (test13, test12_aux):
Tweak overflowing number of digits.
* testsuite/18_support/numeric_limits.cc (test03): New testcase.
