Merge "[svc] Fix "possible loss of data", "division by zero" and "index 5 out of bounds for type" compiler warings"

Change-Id: Ic32eb103d0d7f98c0a16c4e7bdec117faf05df02

For blocks at frame boundary, the selected block size sometimes needs
to be smaller than that was first given. This commit forces such block
size change only between square blocks, so as to avoid the potential
use case containing 32x16 + 16x8 + 16x8, for 1080p sequences.

Local test suggested no visible coding speed difference. Borg test
reveals no difference in terms of compression performance.

"index 5 out of bounds for type" compiler warings

This commit checks if the motion vector associated with the current
mode has been computed in previous mode tests. If possible, skip the
redundant reference block generation and SAD calculation in the
non-RD mode decision process.

For test sequence pedestrian_area 1080p, the runtime goes from
24261 ms to 23770 ms. This does not change compression performance.
The speed-up is mostly around places with consistent motion.

previously the scale functions would always be include regardless of the
CONFIG_SPATIAL_RESAMPLING setting.

All escape conditions that remain require knowledge of best_rd or
best_mode_index.
