[FYI] Make two range_bounds bitfields unsigned
Commit Message
While debugging gdb, I noticed that the bitfields in a range_bounds
were signed, causing the values of these fields to be -1.
I think this is odd; and while we haven't yet committed to boolean
bitfields, I think it is a small improvement to change these types to
unsigned.
