Add a blank line to code_generator.py.

Without this, the line-info test fails.

  python -m pytest python/triton/compiler/code_generator.py

Fails 10/10 times without this blank line, passes 10/10 times with the
blank line.

The failure is in call_noinline and multi_files, both of which generate
incorrect line numbers.

I have absolutely no idea what is going on.
