[PATCH] [sanitizer] Decorate /proc/self/maps.

[Evgeniy Stepanov]

I've had to move the two memory mapping functions to a _libcdep header. Shm_open is not a syscall, and it's implementation in libc includes a lot of platform-specific details that we would not want to replicate in compiler-rt (like searching for a tmpfs/shmfs mount point in mtab).

I've moved the test to sanitizer_common and lost the msan-origin checks - they are not very interesting. In the future it could be nice to add msan-origins as yet another mode we run sanitizer_common tests in.
