golden_test.sh bash script arg problems (should be an easy fix)

Positional order of args changes behavior of script e.g. `-sim`:
```
$fft/bin/golden_test.sh -sim ver 8 1 1port           # Runs one test, as it should
$fft/bin/golden_test.sh          8 1 1port -sim ver  # Tries to run all tests :(
```
