Request for Reviews(M): 7092905: C2: Keep track of the number of dead nodes

[Roland Westrelin]

Bharadwaj,

I Know this is pushed already but I notice one thing that confuses me in this change that I haven't seen discussed before:

Compile::check_node_count() now checks live_nodes() against MaxNodeLimit but check_node_count() is used during parsing and at this point live_nodes() is not correct (it's C->unique(), right?). So depending on the compilation phase we either check the number of uniquely created nodes or the number of live nodes against MaxNodeLimit. To me that makes MaxNodeLimit mostly irrelevant.

Roland.
