Hi,
when generating code for a string concat, the MOST Function always does
some lookup as well as generating a filtering method handle, but only
use these values conditionally. This can also happen repeatedly when
setting up concatenations with primitives (that aren't float or double).
By restructuring this code we can optimize the number of lookups made,
slightly improving startup.
