Add Call Frame Information assembler directives to vector entries so that debuggers display the backtrace of functions that triggered a synchronous exception. For example, a function triggering a data abort will be easier to debug if the backtrace can be displayed from a breakpoint at the beginning of the synchronous exception vector. DS-5 needs CFI otherwise it will not attempt to display the backtrace. Other debuggers might have other needs. These debug information are stored in the ELF file but not in the final binary.
