      Get object properties after `mrb_get_args()` · a137ef12
      dearblue authored 
      ref. #5613

I checked with Valgrind, and the methods that can cause use-after-free are `Array#rotate`, `Array#rotate!`, and `String#byteslice`.
Since `String#rindex` uses `RSTRING_LEN()` indirectly inside the function, no reference to the out-of-bounds range is generated.

      Print error before cleanup in `codegen_error()` · 26338fe6
      dearblue authored 
      Previously, it always pointed to the highest scope as the location of the error.

  - example code `code.rb`

    ```ruby
    huge_num = "1" + "0" * 300; eval <<CODE, nil, "test.rb", 1
    class Object
      module A
        #{huge_num}
      end
    end
    CODE
    ```

  - Before this patch

    ```console
    % bin/mruby code.rb
    test.rb:1: integer too big
    trace (most recent call last):
            [1] code.rb:1
    code.rb:1:in eval: codegen error (ScriptError)
    ```

  - After this patch

    ```console
    % bin/mruby code.rb
    test.rb:3: integer too big
    trace (most recent call last):
            [1] code.rb:1
    code.rb:1:in eval: codegen error (ScriptError)
    ```

      Add `bin/mrbc --no-ext-ops` switch · 6b8582c9

      Print an error if `OP_EXT[123]` is needed when generating mruby binary.
This may be useful for mruby/c.

Inspired by #5590.
