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.
