`INSERT BEFORE` keyword is not supported in current versions gold and
mold linkers. Since we cannot confirm accurately what linker and version
is available on the system and when it will be supported. We test it
with a sample program using the script keywords.
I think the only issue here was that we would erroneously consider
functions which are "in the middle" of the function were stepping to as
a part of the function, and would try to step into them (likely stepping
out of the function instead) instead of giving up early.
