Yukihiro "Matz" Matsumoto f5ca906852 mruby-compiler: fix bare nil? in if/unless to use self as receiver ...

The if/unless nil? optimization called codegen() on the call node's
receiver, but a bare `nil?` is parsed as an FCALL whose receiver is
NULL. codegen(NULL) emits OP_LOADNIL, so the JMPNIL was testing the
literal nil instead of self, making `if nil?` always behave as
`if nil.nil?` (always true) and `unless nil?` always skip its body.
Load self when the receiver is implicit. Fixes #6874.
