Mary Guillemard a6496e3a16 panvk: Properly propagate helper invocations requirement 
Previous changes of the helper invocation pass fixed missing conditional
control flow tracking but this is not enough.

Propagation of the dependency chain also need to handle value outside of
direct predecessors.

This fix "dEQP-VK.graphicsfuzz.cov-nested-loops-sample-opposite-corners"
for real this time.

Fixes: 33fef27356 ("bi: Do not mark tex ops as skip when dest is used by control flow")
