MF9 r254783: Correct implementation of atomic_flag_test_and_set

Approved by:	re
MFS r254728:

  Pull in r182983 from upstream clang trunk:

    Fix handling of braced-init-list as reference initializer within
    aggregate initialization. Previously we would incorrectly require an
    extra set of braces around such initializers.

  Pull in r188718 from upstream clang trunk:

    Handle init lists and _Atomic fields.

    Fixes PR16931.

  These fixes are needed for the atomic_flag type to work correctly in our
  stdatomic.h.

Default net.inet.tcp.experimental.initcwnd10 to 0 in releng/9.2.

Concerns have been raised regarding enabling initcwnd10 by default
in the stable/ branch, so as a cautionary measure, turn this off
for the 9.2-RELEASE.  This sysctl is still available for those
who want to enable this on their own systems.

This is a direct commit to releng/9.2.
