Log Message:
Cherry-pick upstream compiler-rt patches for LLVM sanitizers

Upstream no longer accepts patches for LLVM-8, therefore pull needed changes downstream.

Enhancements:

 * resolved build failured with NetBSD 9.99.3
 * ioctl(2) lists are synced with NetBSD 9.99.3
 * fixes dynamic asan (-fsanitize=address -shared-libasa) crash on init

    Restrict the NetBSD ASan TSD fallback to !ASAN_DYNAMIC

    The fallback to the alternative implementation of TSD with TLS
    is only needed for the static version of ASan for NetBSD.

    The same code cannot be reused for the dynamic version of ASan as
    TLS breaks and TSD code works.

    Sync ioctl(2) list with NetBSD 9.99.3

    Register 36 new ioctl(2) calls.

    Enable NVMM for amd64 as the API has been stabilized.

    Fix build on NetBSD 8.99.38

    With recent changes the dev/nvmm/nvmm_ioctl.h header is no longer
    a standalone NVMM header. Disable it until the NVMM operations will
    stabilize and be included in the ioctl(2) interceptors.
