Summary: * Verify shrink-wrap related bugs. * Validate and release Linaro toolchain binary 2012.11 release. * Collect performance data for different branch costs.

Details: * Validate and release Linaro toolchain binary 2012.11. * Test aarch64 toolchain. All the basic tests PASS except gdbserver. * Collect performance data for branch cost combination. For eembcv1, some combinations have more than 2% performance improvement on PandaBoard THUMB mode. More test results will come later. * Verify shrink-wrap related bugs (http://goo.gl/6fGg5). All pass with the new patch. Native tests are ongoing. Identify the root cause why the copy, which blocks the shrink-wrap optimization for 453.povray benchmark, is not optimized.

Plans: * Finalize the aarch64 toolchain binary release plan. * Collect performance data for branch cost tuning. * Enhance shrink-wrap to optimize the copy.
