Similar to r255816, fix the math for the DELAY() calculation.  It was off
by a really small amount because of the higher timer resolution.

Pull in r196658 from upstream clang trunk:

  CodeGen: Don't emit linkage on thunks that aren't emitted because they're
  vararg.

  This can happen when we're trying to emit a thunk with available_externally
  linkage with optimization enabled but bail because it doesn't make sense for
  vararg functions.

  [LLVM] PR18098.

This should fix clang "Broken module found, compilation aborted" errors when
building the qt4-based dvbcut port.

drm/radeon: agp_info->ai_aperture_size is in bytes, not Mbytes

This fixes radeon_agp_init() and gtt_size is now correct. However, this
is not enough to make Radeon AGP cards work: ttm_agp_backend.c isn't
implemented yet.

Restore a vital comment nuked in r259016.
cxgbe(4): save a copy of the RSS map for each port for the driver's use.
drm/radeon: radeon_dp_i2c_aux_ch() must return 0 on FreeBSD

The code was unmodified compared to Linux and returned the amount of
received bytes from the i2c bus. This led to non-working i2c bus and
failure to eg. read monitor's EDID, if connected to DisplayPort.

When comparing device IDs, make sure that they have the same type
(like NAA assigned) and identify the same entity (like device or port).
Otherwise there can be false positives since at least some models of
Seagate disks use same IDs for the whole device and one of its ports.

Fix build with 'crypto' and 'zfs' in the same kernel.  This was the path
of least pain I could find.
o Build syscons(9)'s splash support if both sc and splash are enabled.
o Include opt_splash.h for vt(9) to know when splash device is enabled.
o Build logo_freebsd.c only if splash and vt are enabled.
o Include opt_compat.h to know when we have to respect compatibility.

Use correct casts in gcc's emmintrin.h for the first arguments of the
following builtin functions:

* __builtin_ia32_pslldi128() takes __v4si instead of __v8hi
* __builtin_ia32_psllqi128() takes __v2di instead of __v8hi
* __builtin_ia32_psradi128() takes __v4si instead of __v8hi

This should fix the following errors when building the LINT kernel with
gcc:

sys/crypto/aesni/aesni_wrap.c:191: error: incompatible type for argument 1 of
'__builtin_ia32_psradi128'
sys/crypto/aesni/aesni_wrap.c:195: error: incompatible type for argument 1 of
'__builtin_ia32_pslldi128'
