  [AIX][XCOFF] generate eh_info when vector registers are saved according to the traceback table.

Summary:

generate eh_info when vector registers are saved according to the traceback table.

struct eh_info_t {

unsigned version;       /* EH info version 0 */
#if defined(64BIT)

char _pad[4];           /* padding */
#endif

unsigned long lsda;     /* Pointer to Language Specific Data Area */
unsigned long personality; /* Pointer to the personality routine */
};

the value of lsda and personality is zero when the number of vector registers saved is large zero and there is not personality of the function
