ec64d037bd0446bc1c48f711f11f7ca4ad911241 cond_stack/mask_stack for CPU backend
This is enough to let the next runtimecolorfilter filter draw.
Mostly this just apes the cond/mask stacks from SkSLByteCode.cpp.
The point of most interest is that we can skip forward kBranchIfAllFalse
if we make our side effects (stores) conditional.
My reasoning here is that a forward branch-if-all-false instruction must
always be a performance optimization only; it's always got to be safe to
not take the branch, as one of your lanes could very well not be false.
