that file would still cause a leak similar to #9099.

checks were insufficient to prevent 'size -= RIFF_HEADER_SIZE' from
rolling over causing ChunkVerifyAndAssign to over read. the new checks

with loop_compatibility disabled (the default), non-zero loop counts
will be incremented by 1 for browser rendering compatibility. the max,
65535, is a special case as the muxer will fail if it is exceeded; avoid
increasing the limit in this case. this isn't 100% correct, but should
be close enough given the high number of iterations.

with gcc-4.8, clang-4.0.1/5 this is no faster (actually up to 2x slower)
than the code generated for memset (0x01010... * dst[-1]). shuffles in
