libstdc++: Fix some tests that fail with -fexcess-precision=standard
libstdc++-v3/ChangeLog: * testsuite/20_util/duration/cons/2.cc: Use values that aren't affected by rounding. * testsuite/20_util/from_chars/5.cc: Cast arithmetic result to double before comparing for equality. * testsuite/20_util/from_chars/6.cc: Likewise. * testsuite/20_util/variant/86874.cc: Use values that aren't affected by rounding. * testsuite/25_algorithms/lower_bound/partitioned.cc: Compare to original value instead of to floating-point-literal. * testsuite/26_numerics/random/discrete_distribution/cons/range.cc: Cast arithmetic result to double before comparing for equality. * testsuite/26_numerics/random/piecewise_constant_distribution/cons/range.cc: Likewise. * testsuite/26_numerics/random/piecewise_linear_distribution/cons/range.cc: Likewise. * testsuite/26_numerics/valarray/transcend.cc (eq): Check that the absolute difference is less than 0.01 instead of comparing to two decimal places. * testsuite/27_io/basic_istream/extractors_arithmetic/char/01.cc: Cast arithmetic result to double before comparing for equality. * testsuite/27_io/basic_istream/extractors_arithmetic/char/09.cc: Likewise. * testsuite/27_io/basic_istream/extractors_arithmetic/char/10.cc: Likewise. * testsuite/27_io/basic_istream/extractors_arithmetic/wchar_t/01.cc: Likewise. * testsuite/27_io/basic_istream/extractors_arithmetic/wchar_t/09.cc: Likewise. * testsuite/27_io/basic_istream/extractors_arithmetic/wchar_t/10.cc: Likewise. * testsuite/ext/random/hoyt_distribution/cons/parms.cc: Likewise.
