While there is a reference to -ftree-dse being turned on with -O optimization
in both the manpage and the online docs (see e.g.
http://gcc.gnu.org/onlinedocs/gcc-4.2.0/gcc/Optimize-Options.html#Optimize-Options),
that is the only reference to this option.  The specific behavior of this
option does not appear in either the manpage or the online docs.

Confirmed to exist in 4.2.0 and 4.2.2 docsets.  Maybe more?
