CPython math.nan is positive with regards to copysign.  The signaling bit
(aka sign flag) was incorrectly set.

In addition, REPR_C and REPR_D should only use the _true_ nan to prevent
system crash in case of hand-crafted floats.  For instance, with REPR_C,
any nan-like float following the pattern
`01111111 1xxxxxxx xxxxxxxx xxxxx1xx` would be switched to an immediate
object or a qstr string.  When the qstr index is too large, this would
cause a crash.

This commit fixes the issue, and adds the relevant test cases.

3dc324d3f1 tests: Format all Python code with black, except tests in basics subdir.
This adds the Python files in the tests/ directory to be formatted with
./tools/codeformat.py.  The basics/ subdirectory is excluded for now so we
aren't changing too much at once.

In a few places `# fmt: off`/`# fmt: on` was used where the code had
special formatting for readability or where the test was actually testing
the specific formatting.

fde54350a8 tests/float: Convert "sys.exit()" to "raise SystemExit".
The latter is shorter and simpler because it doesn't require importing the
sys module.
