[Bug c/40530] New: Suggestion: -Wsignless-bitfields

[h dot b dot furuseth at usit dot uio dot no]

I imagine a bitfield which does not specify 'signed' or 'unsigned'
will often be a bug in user code - maybe the programmer did not
know or did not remember that 'int i:3;' can be unsigned.

I suggest a warning for that in user code.  Maybe included in
-Wextra, but I cannot guess how much such correct code is around.

The warning should be quiet about system headers, which may know
how the system compiler treats such bitfields.
