Bring x86 to parity with arm64, similar to commit 25b84002afb9
("arm64: Support Clang UBSAN trap codes for better reporting").
Enable the output of UBSAN type information on x86 architectures
compiled with clang when CONFIG_UBSAN_TRAP=y. Currently ARM
architectures output which specific sanitizer c
