1. The global TrimMode property is set to 'copy'

Unfortunately we can only determine the latter once the PrepareForILLink target has run, and we need to know this before that
target has executed, so we do a simpler estimation: we just look at the 'TrimMode' property, and assume we're not trimming anything
if its value is 'copy'.
