This just happened not to crash/assert because all loops have at
least 1 if-statement and due to a second bug we end up matching
the same ENDIF to exit both the iteration over the if-statment
and the loop.
The second bug is fixed in the following patch.
Fixes: 386d165d8d09 ("tgsi/scan: add a new pass that analyzes tess factor
writes")
