Adam Klein fb16583179 Retain source order when hoisting sloppy block functions 
This involved adding a count_ member to SloppyBlockFunctionMap, so
to avoid making DeclarationScope larger, this patch makes the
creation of the map lazy, thus reducing the size of DeclarationScope
by several words in the process.
