Kees Cook f4626c12e4 ubsan: Add awareness of signed integer overflow traps 
On arm64, UBSAN traps can be decoded from the trap instruction. Add the
add, sub, and mul overflow trap codes now that CONFIG_UBSAN_SIGNED_WRAP
exists. Seen under clang 19:

  Internal error: UBSAN: unrecognized failure code: 00000000f2005515 [#1] PREEMPT SMP

Reported-by: Nathan Chancellor <nathan@kernel.org>
Closes: https://lore.kernel.org/lkml/20240411-fix-ubsan-in-hardening-config-v1-0-e0177c80ffaa@kernel.org
Fixes: 557f8c582a ("ubsan: Reintroduce signed overflow sanitizer")
Tested-by: Nathan Chancellor <nathan@kernel.org>
