The macOS catalina compiler produces an error for __int128_t

Create a new X86Int128Union type and use the vector type for

Create both atomic16_read_ro and atomic16_read_rw.
Previously we pretended that we had atomic16_read in system mode,
because we "know" that all ram is always writable to the host.
Now, expose read-only and read-write versions all of the time.

For aarch64, do not fall back to __atomic_read_16 even if
supported by the compiler, to work around a clang bug.

The entire contents of the header is host-specific, but the
existence of such a header is not, which could prevent some
host specific ifdefs at the top of the file for the include.
