When the stub return a heap number we do a state transition to a version HEAP_NUMBER that can handle -0. There is room for further improvement in the typefeedback for the case of -0. This change however does not address this and only fixes the acute issue.

When descending the dominator tree we used to collect side effects from all blocks between the dominator and the dominated blocks in the block ordering. This could include blocks that do not appear on paths from the dominator to the dominated and unnecessarily removed available values from the GVN map.

Better support for 'polymorphic' JS and external arrays Allow keyed store/load stubs to switch between external array and fast JS arrays without forcing a state transition to the generic stub. There CL consists of two pieces of functionality. First, code stubs for fast element arrays don't immediately transition to the MEGAMORPHIC state when there's a map mismatch. Second, two ICs are cached per map for fast elements, the MONOMORPHIC version, and a new MEGAMORPHIC version that handles two or more different maps and dispatches to shared stubs to perform the array operation.

Handle all kind of arguments in the ToBooleanStub. While this is not very thrilling in itself, it is one of several steps to add type recording to this stub. Removed a duplicate check for null in the ARM stub and made a tiny simplification, removing a sub instruction. As a side note, this change has some positive impact on the performace, e.g. imaging-darkroom is 8.3% faster and ws-ieee754conv is even 19.9% faster. No idea why the speedup is so big in some cases, but never look a gift horse in the mouth... ;-) Review URL: http://codereview.chromium.org/7042004 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@7926 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
