Doubles amount of space allocated for translation blocks.  This is
needed, particularly for Hexagon, where a single instruction packet may
consist of up to four vector instructions.  If each vector instruction
then gets expanded into gvec operations that utilize a small host vector
size the TB blows up quite quickly.
