This commit adds constants for unsigned values. Currently we can use `-`
to mean "unsigned", but I think having a specific name makes Fiddle more
user friendly. This commit continues to support `-`, but introduces
negative constants with "unsigned" names
I think this will help to eliminate [this
code](3a56bf0bcc/lib/mjit/c_type.rb (L31-L38))
