Subject: bytecode: set register type to `REG_PTR` even if not used
X-Git-Tag: v2.13.0-rc1~449

bytecode: set register type to `REG_PTR` even if not used

There was no need to set the field when using filter as the next
instruction would assume that the top of stack is a `REG_PTR`.

With the upcoming capture feature, we need to ensure this field is
consistent for extraction.
