The comment made it look like the condition code was dropped from
the extra add instruction, while it actually was handled properly.

Thus, the comment was misleading while the code itself did the right
thing.

Also clarify the comment indicating that we use the full three-operand
form of the add instruction.

vp8_vpxyv12_copy_y_neon is slower than vp8_vpxyv12_copy_y_c.

Modified the non-rd rate_mv calculation and moved it after sub-pixel
motion search is done.

Adding a --(enable|disable)-webm-io flag to control WebM container input and
output support. For now, enabling WebM IO by default only when there is a C++
compiler. Doing so because eventually we will move WebM IO to libwebm and it
is built using C++.

The block coding skip flags are assigned in the normal RD mode
decision loop. They are then used in the final encoding stage.
In the non-RD mode decision, the forward transform and quantization
stages are replaced by modeling based on SSE and variance of
prediction residues. This commit applies reset to this array in
the non-RD coding mode.

This commit moves the position where rdmult is saved to make sure it
is the correct value. Prior, an uninitialized value may be saved and
restored.

This function was subsumed by nonrd_use_partition, hence removed.

This commit unifies the non-RD partition use cases for both fixed
and variable block sizes. Deprecate and remove the separate function
for fixed partition type only.

This commit allows the non-RD mode decision process to return the
rate and distortion costs associated with the selected mode.
