Fix handle OP_TABLE_COPY issue Fix loader handle OP_BLOCK/IF/LOOP issue if type_index is larger than 256 Fix loader handle OP_GET_GLOBAL, allow to change to GET_GLOBAL_64 for aot compiler similiar to handling OP_SET_GLOBAL Refine loader handle OP_GET/SET/TEE_LOCAL, disable changing opcode when source debugging is enabled, so as no need to record the change of opcode Refine wasm_interp_interp_frame_size to reduce the wasm operand stack usage Signed-off-by: Wenyong Huang <wenyong.huang@intel.com>
