Log:
fix PR8102, a case where we'd copyValue from a value that we already
deleted. Fix this by doing the copyValue's before we delete stuff!

Log:
Fix a serious performance regression introduced by r108687 on linux:
turning (fptrunc (sqrt (fpext x))) -> (sqrtf x) is great, but we have
to delete the original sqrt as well. Not doing so causes us to do
two sqrt's when building with -fmath-errno (the default on linux).

use. This fixes PR8068
