Summary: * Investigate shrink-wrap result. * Prepare for Linaro toolchain binary release, script merge and aarch64 test.

Details: 1. Investigate shrink-wrap result of function Ray_In_Bound. By default, ARM/MIPS/PPC/X86 toolchain can not shrink-wrap the function. For ARM, there is copy "r6 = r1" which blocks the optimization. By hacking the assemble code, I got ~3% performance improvement for 453.povray benchmark. 2. Setup AARCH64 simulation environment by following http://www.linaro.org/engineering/armv8. 3. Write scripts to collect branch cost performance. It will take weeks to get all the benchmark results. 4. Smoke test Linaro toolchain binaries 2012.11 release. 5. Try export crosstool-ng trunk to a bzr project. bzr fast-import always fail on Ubuntu 10.04, but it works on 12.04. 6. RM toolchain related work.

Plans: * Collect performance data for branch cost tuning. * Linaro binary toolchain 2012.11 release. * Verify shrink-wrap bugs.
