ErlSubBin is a large struct that often dwarfs the region of memory
it points at, and it's common for them to refer to a ProcBin which
must be kept around as long as the SubBin lives, using up even more
heap space and keeping the referenced binary alive regardless of
how small the sub-binary is.

is now changed to r20.
