In branch elimination phase, control paths are updated when visiting the nodes. We first create a control path and then check if it is same as the exisiting one. If it is the same we discard the newly created one. Since these are created in the zone memory the memory will not be released till the entire pass is over. This cl changes it to first check if the control path has changed and create a new path only if it has changed.

Each reducer now has a virtual reducer_name function, returning its name (the name of the class containing this reducer). This gets displayed when using the --trace_turbo_reduction flag. Also when using this flags more messages are displayed. Actually when a node is replaced in-place (which is called an update of the node), other reducers can still update it right after the in-place replacement. When a node is really replaced (not in-place), then we stop trying to apply reducers to it before we propagate the reduction through the relevant nodes. Before a message got printed only for the last reduction it went through. So in case a node was reduced in-place several times in a row, only the last update was printed, or none at all if after being reduced in-place it got reduced by being replaced by another node: only the non-in-place replacement was showed. Now each time an in-place reduction is applied to a node, a message gets printed.

Getting elements, querying length or copying elements are now const functions. Drive-by fix: Noticed a few more getters that should be const. Add a comment to ArrayList functions that are static functions.

These macro operators represent a conditional eager deoptimization exit without explicit branching, which greatly reduces overhead of both scheduling and register allocation, and thereby greatly reduces overall compilation time, esp. when there are a lot of eager deoptimization exits.

Removes a branch that checks for a condition that has been checked on dominators of the branch. This introduces a new reducer that propagates the list of checked conditions (and their boolean values) through the control flow graph. If it encounters a branch checking a condition with a known value, the branch is eliminated. The analysis relies on loops being reducible: if a condition has been checked on all paths to loop entry, then it is checked in the loop (regardless what of the conditions checked inside the loop). The implementation is fairly naive and could be improved: - all the operation on the condition lists could be made allocation-free when revisited. - we could try to use a map structure rather than a linked list (to make lookups faster). - the merging of control flow could be changed to take into account conditions from non-dominating paths (as long as all paths check the condition).
