Zhao Jiazhong	017c12b3c5	[loong64] Optimize GenerateSwitchTable ... We should use pc relative branch instruction rather than loading target address from memory for better performance. Besides, just like arm64, currently we assume that none of our relocation types are pc relative pointing outside the code buffer nor pc absolute pointing inside the code buffer.
