[PATCH] D45047: MSan: introduce the conservative assembly handling mode.

FWIW, we couldn't enable this mode in KMSAN by default.
Turned out people are passing all sorts of random pointers into inline assembly in the kernel (sometimes those arguments are unused by the assembly itself), and unpoisoning those just triggers page faults.
Guess it's worth looking into instrumenting the assembly with calls, so that we can check the pointers at runtime.
