Yura Yaroshevich 01c2c325bd Faster erase buffer within FrameCombiner with -Oz opt level. 
Previous erase implementation on clang with -Oz optimization
leve produced effectively per element zeroing, causing
unnecessary CPU usage on mobiles.
Using zero-initialization is both shorter and easier to
optimize for clang:
