Yukihiro "Matz" Matsumoto b4f6450509 mruby-compiler: do not flip + and - opcode for negative literal ...

The peephole in gen_addsub() rewrote `q + -n` into OP_SUBI n (and
`q - -n` into OP_ADDI n) by negating n. For numeric receivers this is
equivalent, but for receivers overriding + or - the runtime fallback
dispatches the flipped method, losing the original operator. Restrict
the fold to non-negative immediates; negative falls through to the
normal OP_ADD/OP_SUB path with LOADI of the literal value.
