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.

si->layers is validated prior to assignment; add an assertion prior to
first use as a loop bound

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.
