Fix some bugs to make the jar file verification test passed using c1 compiler. Fix bugs: 1. Value of vmreg stands for a register. 2. Fix long register endianness bug. 3. The long arithmetic is implemented by C, we should implement it using assemble later. 4. The register of safepoint_poll is allocated and its return address manually set. 5. safepoint_return use register A0.
