Is archives the right word?  The --enable-checking=release by default is
turned on whenever it is a release branch, checked by whether gcc/DEV-PHASE
is not experimental, and generally applies to everything but the GCC trunk.

I would certainly not say that rtl checking is very expensive, it is
somewhat expensive, but I'm using it in all my bootstraps and others are as
well.  On the other side, fold checking is extremely expensive.

So perhaps

The @samp{rtl} checks are expensive and the @samp{df},
@samp{fold}, @samp{gcac} and @samp{valgrind} checks are very expensive.
