teach sparse about -funsigned-bitfields
Currently, Sparse treats 'plain' bitfields as unsigned.
However, this is this is inconsistent with how non-bitfield integers
are handled and with how GCC & clang handle bitfields.
So, teach sparse about '-funsigned-bitfields' and by default treat
these bitfields are signed, like done by GCC & clang and like done
for non-bitfield integers.
Also, avoid plain bitfields in IR related testcases.
