Jonas Paulsson 1af13e6948 [CodeMetrics] Don't let extends of i1 be free. ...

getUserCost() currently returns TCC_Free for any extend of a compare (i1)
result. It seems this is only true in a limited number of cases where for
example two compares are chained. Even in those types of cases it seems
unlikely that they are generally free, while they may be in some cases.

This patch therefore removes this special handling of cast of i1. No tests
are failing because of this.

If some target want the old behavior, it could override getUserCost().
