For non-rd pickmode:
best_pred_sad, computed for NEWMV-last, is only used for
skipping golden non-zero modes. Add condition to avoid this
computation if not used (i.e, if golden nonzero modes are not used).
And remove code for computing best_pred_sad for NEWMV-golden,
since that sad is not used.
No change in behavior; small speed gain (~1%) for svc encodes.

Rename vp9_dct_sse2.c to vp9_dct_intrin_sse2.c for vp9 and
rename dct_sse2.c to dct_intrin_sse2.c for vp10 to avoid
duplicate basenames.
Actually vp9_fwht4x4_mmx/sse2() and vp10_fwht4x4_mmx/sse2()
are identical. TODO: They should be unified later if there is
no intention to keep a duplicate.

C does not allow for shifting into the sign bit of a signed
integer, and the two instances here become signed ints via
promotion. Explcitly cast them to unsigned MEM_VALUE_T to
avoid the problem.

Followed the code style of other lpf fuctions.
These 2 functions put 2 rows of data in a single xmm register,
so they have similar but not identical filter operations,
and cannot share the same macros.

Apple's version format specification is strictly checked on app
store submission, even for embedded frameworks:
http://apple.co/1WgelY1
The build version number should be a string comprised of
three non-negative, period-separated integers with the
first integer being greater than zero. The string should
only contain numeric (0-9) and period (.) characters.
So that's room for "1.5.0" but not for "1.5.0-906-g656f9c4".
The full version returned from 'version.sh --bare' is now
embedded under a 'VPXFullVersion' custom key in the Info.plist,
so it can still be extracted from the resulting framework.

vp9_diamond_search_sad_avx was disabled in:
057c1c4 disable vp9_diamond_search_sad_avx
this removes a missing prototype warning as the prototype is no longer
included in vp9_rtcd.h. the file can be restored if someone gets around
to fixing the issue.

Many codes require -mstackrealign flags. Although -mstackrealign has
been already added to CFLAGS of some modules, SIGSEGV occurs in other
modules than those modules.
The best way may be to find causes and to fix them. However, we
cannot know those causes until SIGSEGV occur really. In addition, if
SIGSEGV occurs in other programs, it will be fatal.
So adding -mstackrealign flags to CFLAGS unconditionally is
reasonable.

Move the logic for rechecking zeromv on denoised block out to simplify

VP9_PICKMODE_CTX_DEN which is only used when denoiser is enabled.

The inlining mirrors what was done with the low bit depth
inter_predictor. And the new highbd_inter_predictor name is more
consistent with other high bit depth functions.
