[Auto mailings of changes to Lily Issues via Testlilyissues-auto]

We don't have this (yet), the code just does extern unsigned long GC_free_space_divisor;. But still I think it's a good idea because it allows the user to change it, should there ever be a need.

[issues:#5681] Instrument and improve GC time

Setting GC_free_space_divisor to 1 decreases GC time on GUILE v2 from
2.1s to 1.75s, a 17% speedup for the Mozart horn concerto example

Don't try to tune the GUILE 1.8 GC if we are on GUILE 2.
