Remove +s
It doesn't seem worth >200 lines of C and Perl to save ~50 lines in insns.dat.
In order to make this work I had to rename sbyte16/sbyte32 so that
they can take an ordinary size suffix (their size suffix was formerly
treated specially).
This fixes one disassembly bug: 48C7C000000080 disassembles to mov
rax,0x80000000, which reassembles to B800000080, which loads a
different value.
