[9] RFR(XS): 8147876: ciTypeFlow::is_dominated_by() writes outside dominated array

[Tobias Hartmann]

Hi,

please review the following patch:

https://bugs.openjdk.java.net/browse/JDK-8147876
http://cr.openjdk.java.net/~thartmann/8147876/webrev.00/

ciTypeFlow::is_dominated_by() write outside the 'dominated' array because it's size is too small. The problem is that the number of ciBlocks is not equal to the Blocks used by ciTypeFlow (there is a 1:n relation). Therefore, we should use block_count() instead of _methodBlocks->num_blocks().

Thanks,
Tobias
