Gatlin Newhouse 7424fc6b86 x86/traps: Enable UBSAN traps on x86 
Currently ARM64 extracts which specific sanitizer has caused a trap via
encoded data in the trap instruction. Clang on x86 currently encodes the
same data in the UD1 instruction but x86 handle_bug() and
is_valid_bugaddr() currently only look at UD2.

Bring x86 to parity with ARM64, similar to commit 25b84002af ("arm64:
Support Clang UBSAN trap codes for better reporting"). See the llvm
links for information about the code generation.

Enable the reporting of UBSAN sanitizer details on x86 compiled with clang
when CONFIG_UBSAN_TRAP=y by analysing UD1 and retrieving the type immediate
which is encoded by the compiler after the UD1.

[ tglx: Simplified it by moving the printk() into handle_bug() ]
