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!
The testcase only repros the problem on my system with valgrind.

fix a bug in my licm rewrite when a load from the promoted memory
...
location is being re-stored to the memory location. We would get
a dangling pointer from the SSAUpdate data structure and miss a
use. This fixes PR8068
